"MuYong read bucket don’t read chung, farmers read pus don’t read oboro. Rice reads japonica rice but not stalks, while sunny rice does not read eyes … …” Many tongue twisters that Chinese may not be able to read smoothly were read completely by foreigners, and such interesting pictures appeared at the launching ceremony of the "Chinese Bridge" competition.

　　On September 1st, the launching ceremony of the 19th "Chinese Bridge" World College Students Chinese Competition and the 13th "Chinese Bridge" World Middle School Students Chinese Competition was held in Beijing. Many innovations in competition system and technology of this year’s "Chinese Bridge" were introduced at the event site.

　　Popular players playing flying flowers on the spot make it interesting.

　　CCTV presided over the topic to find out the Chinese Bridge and tell the story of China.

　　Can "crooked nuts" also play "flying flower order" At the launching ceremony, several champions took the title of "Moon" and received more than a dozen poems in one breath. Even with such literary attainments, they were once again "difficult" by the examination questions given by two famous CCTV mouths, Kang Hui and Zhu Guangquan.

　　Zhu Guangquan described the school opening scene with the rhyme of baffled sign language translation. Egyptian player Liu Zhengxi tactfully discovered the key message of "confiscation of mobile phones" and successfully solved the "Zhu-style puzzle", which caused the audience to burst into laughter. Zhu Guangquan’s exam was just a warm-up, and Kang Hui’s tongue twister really stunned the three champions. "Ears make people listen to the music, but they don’t read the mountains, while fire makes them read the lights, but they don’t read the clarity." Zhu Xun said that Kang Hui’s tongue twister read out the aesthetic feeling of Chinese melody, and he also felt "how he got into CCTV in those days". Kang Hui’s tongue twister exam finally came to an end in the laughter of the audience.

　　"Champion Group" players draw lots

　　As a bridge, Chinese is the best in the world. As a carrier of cultural communication, Chinese not only has a unique aesthetic feeling, but also has a strong interest. The activity of "Chinese Bridge" hopes to cross cultural differences, let young people all over the world discover the charm of China language, and also hope to better spread China culture through Chinese.

At first glance, the comic narrative setting of the new drama "Yulouchun" is very light; Looking closely, the drama has some bright spots in the integration of traditional cultural elements and image expression.

Author: and song

Unexpectedly, the beautiful Luoshen dance has a new version, this time in the costume drama "Yulouchun".

Wu Yuehong, the grandson’s eldest daughter-in-law played by Yoko Spicy Eyes, accompanied by playful music, walked away to her husband, Sun Shijie, clumsily and confidently imitating Luo Shen’s "body flying fast and limping".

Sun Shijie, who "fled", commented that this dance was "effective from the east", but the contrast between the slim Luo Shen in the painting and Wu Yuehong’s "Luo Shen" plus version outside the painting made many netizens laugh, which also opened the corner of the light narrative of the play.

There are many scenes that make people laugh. In the latest story, the heroine Lin Shaochun (White Deer) uses pollen allergy to "seal" her beauty and successfully escapes from choosing a concubine.

What kind of people are these and what interesting stories are they telling?

"Fast-forward" version of the ancient style, shaking out dense "baggage"

"Yulouchun" tells the story of Lin Shaochun, who was displaced from the street in his family. By chance, he fell in love with Yulou (Wang Yizhe), the son of the records of the dynasty, and then married into the grandson of Zhong Ming, who was a food eater, and then started a relaxed and interesting story of "family happiness".

Judging from the picture, "Yulouchun" looks like an open ancient book. The opening part follows a shadow play along the street, passing through pavilions, streets and lanes, "embracing" three religions and nine streams and princes and nobles, and positioning itself in the main venue of the story-the prominent Sun family in the "directory" introduction.

The fast-forward of "shadow play" made the characters appear one after another, and the stories immediately became "lively", and the comedy style began to appear. In the Sun family, funny stories were staged one by one-

Wu Yuehong, the eldest daughter-in-law, not only imitates Luo Shen, but also comes from a family of military officers. She has just been taught by her mother-in-law to be "considerate and caring" for her husband, and then she turns around and shoulders her burly husband and leaves.

Xu Fengqiao (Gina), the third daughter-in-law, is "a royal husband with skills". No matter how many reasons he finds to cover up staying out at night, he does not fall behind in "unique ways" such as kneeling abacus and eating Chili peppers.

In Yulouchun, various humorous inversions are still presented on different occasions. For example, in order to test whether Lin Shaochun pretended to be greedy for vanity because he declined his pursuit, Yulou invited his friends to pretend to be a dude and forced Lin Shaochun to drink, but he was ready to stand up at the critical moment and stage a drama of "saving the beauty by a hero", but he did not want Lin Shaochun to easily resolve the "crisis".

A series of hilarious plots also provided an entrance for the audience to quickly enter the show.

As far as the 10 episodes updated in the first week are concerned, the story lines of "Yulouchun" in Sun’s mansion, namely, the daily life of the male and female host, the acquaintance and love of the male and female host, and the heroine’s redress for the father, go hand in hand, including more characters, which makes the plot progress contradictory and motivated.

The multi-line simultaneous development of the whole drama has also created more contact points for the integration with traditional culture. In the daily life of Sunjia Mansion, shadow play of intangible cultural heritage is used in series; The feelings of Lin Shaochun and Sun Yulou have warmed up in the performances of one hundred theatrical troupes. Traditional cultural elements such as pipa, guqin, flower arrangement, incense and so on are all presented.

In terms of scenery setting, according to Luan Hexin, production designer, the play refers to the collocation of traditional painting colors in China and the layout of the new Chinese style structure and environment, and is associated with different characters and stories, "to present a warm image for the audience".

In terms of modeling, Song Xiaotao, the modeling director, chose a light color scheme for the needs of the drama series to show all kinds of life, and embellished it with many non-legacy techniques under the details. For example, Gu embroidery, which originated in the Ming Dynasty, is used in clothing production, and delicate and elegant flowers are also used in jewelry production besides traditional crafts such as silk-cutting and treasure-embedding.

　"Small personality" leads to "family happiness"

Regardless of genre and form, a drama is still telling stories and shaping people. For this humorous costume drama, the "family fun" character of the characters promotes the "family fun" trend of the plot.

Several groups of Sun family characters with different personalities give the story a different foothold, which can be humorous, ridiculous, reversed and serious. This is most obvious among several female characters in the Sun family.

Sun Jia’s eldest daughter-in-law, Wu Yuehong, is a typical "humorous bear", who will watch Luo Shen make a beautiful imitation makeup and dance swords and recite poems;　

Su Yingxue, the second daughter-in-law, is "partial to literature and art" and loves to play a little temper, but she enjoys hearing good melody.

Adrian Xu, the third daughter-in-law, is arrogant and provocative, and she will never suffer.

Lin Shaochun, who is about to marry into Sun Fu, obviously feels more "heavy responsibility on her shoulders" than other women: she lost her parents overnight because of her father’s injustice in childhood, and she is strengthening herself through experience, whether she is studying in a troupe or choosing a concubine in the palace.

The characters of several women have become the "basic disk" of the plot, and the characters with their own characteristics make the movements between paragraphs complement each other, humorous but not too noisy; In the daily life of husband and wife, father and son and sister-in-law, it can be seen that the drama series thinks about the relationship between individuals and families, but it is not too deep; Vivid characters and diverse emotional relationships jointly set off the daily fireworks in the deep house compound.

All the people outside Sun Fu also stick to their own principles.

Yao Dizhu, Xu Fengqiao’s cousin, never refused to be "taken care of" in marriage matters, and skillfully used her mind to make herself unsuccessful in the draft, not seeking prosperity, but seeking "one person for life." Liu Sanjue, the master of the troupe, has mastered the stunt that can make girls in that era "live" and pretend to be boys without revealing their flaws. However, Liu Sanjue always emphasized to his disciples that "this skill cannot be exchanged for unjust utilitarianism".

Although these characters are in the background of ancient society, they all dare to break free from the shackles of the times. The drama connects with the modern audience with the logic of ordinary people-bravely pursuing marriage and love, but also sticking to the bottom line of personal value.

The brisk pace, dense baggage and happy family atmosphere are the obvious characteristics of Yulouchun at present. However, there is still room for improvement in plot narration and bridge design. With the advancement of the story, I look forward to better performance in the future.

Olympic games

When buying a notebook computer, once the purpose, budget and size are determined, the CPU (Central Processing Unit) model is undoubtedly the top priority screening condition. After all, it is the "brain" of the notebook.

A more powerful CPU can help users process tables, load web pages, edit photos and play games faster. But at the same time, a high-performance processor also means that its battery life will be worse.

Therefore, when choosing the key components of notebook — — Before CPU, we should first determine what we are going to do with the notebook.

What kind of CPU should I use for different purposes?

At present, the notebook CPU is still dominated by Intel. In view of the fact that the notebook equipped with AMD Ryzen mobile processor has not been officially listed, and AMD has no mobile products at present, this article only introduces Intel’s products.

So, which CPU is the best for you? As long as the purpose and budget are clear, it’s easy to do it. Qiushi Lab has compiled a table for everyone, and it’s clear at a glance which series of CPU to buy for what purpose:

What do you think of the CPU model?

Intel processors seem to be various, but it is not difficult to distinguish them. Let’s take the common Core I series CPU as an example: first, the brand series, with performance of i7>i5>i3, but generally i5 can meet the needs of most users (except Y series, which will be discussed below).

The brand series is followed by the specific model, and the first one represents algebra (only Core applies this rule). Here, it is recommended that office users try their best to purchase the newly launched 8th generation products within the budget.

Two to four digits are SKU digits (Y series is the last two digits). The larger this number, the higher the performance of the CPU. For example, the performance of i5-7300U is better than that of i5-7200U.

If the suffix is u, it means that the product is a low-voltage version. U series is the most mainstream and common type, which is more suitable for office users.

If the suffix is Y, it means that the product is a Y series with ultra-low power consumption. In fact, it is renamed from the Core M series, which is different from the conventional Core products in performance.

Users with game and high performance requirements choose products with HQ and HK suffixes, which are signs of standard voltage, while the former does not support overclocking, but the latter allows users to overclock.

As for the M suffix refers to the mobile version of the product, which appears in the Xeon E series, other suffixes are rare in the new CPU models in recent two years, so I won’t repeat them here.

Detailed explanation of different processor series

Xeon E series: professional high-end users

Xeon E series processors mainly appear on top mobile workstations. Notebooks equipped with Xeon E can efficiently perform 3D animation, complex engineering simulation and other professional work, with very strong performance. But at the same time, this kind of notebook is not strong in endurance and very expensive.

Mainstream models: Xeon E3-1535M v6, Xeon E3-1505M v6, Xeon E3-1505M v5.

HQ/HK Standard Voltage Series: Professional Design/High-end Games

For users engaged in video production, graphic design and high-end games, the CPU with HQ and HK as the follow-up standard voltage can provide stronger performance, but it will generate more heat than the CPU with U as the follow-up, and its battery life will be much worse.

Because of the greater heat dissipation pressure, notebooks equipped with HQ and HK standard voltage series CPU are basically out of touch with the word "thin".

HQ and HK suffixes also have different meanings, both of which are standard voltage series, but the CPU following HK allows users to overclock, while HQ cannot. The topic of overclocking will involve more advanced knowledge, so I won’t talk about it here.

Mainstream models: i7-7920HQ, i7-7820HK, i5-7440HQ and i5-7300HQ.

U low voltage series: the office choice of the general public

U-series CPU is a product with average performance and endurance, such as i5-7200U and i5-8250U. For most users who just surf the Internet, watch videos, process tables and documents, and occasionally trim pictures, the performance of U-series CPU is enough.

At present, Intel has launched the 8th generation Core i5 and i7 processors, and the number of cores/threads has been increased to 4 cores and 8 threads, which is stronger in multitasking than the 7th generation Core i5 and i7 processors. Therefore, it is recommended that you give priority to purchasing products equipped with the 8th generation Core processors.

8th Generation i7, i5 and i3 Processors

Mainstream models: i7-8650U, i7-8550U, i7-7600U, i7-7660U, i5-8350U, i5-8250U, i7-7567U and i5-7200U.

Y/M series: fanless design, light and portable.

Y-series is a trap for some users. Although they also have seemingly strong names such as i5 and i7, in fact, i5 and i7 of Y-series are renamed from m5 and m7 of M-series, so although they are also i5 and i7, there is a certain gap between them and the performance of U-series.

However, the Y/M series CPU benefits from its ultra-low TDP, which can be used in ultra-thin notebooks with fanless design. Therefore, although its performance is not strong, its battery life is still not bad, and it is suitable for light users who pursue lightness and portability and have low performance requirements.

Mainstream models: Core i7-7Y75, Core m7-6Y75, Core i5-7Y54, Core m5-6Y57.

Celeron/ Pentium/ Atom series: budget shortage, light use.

Celeron and Pentium CPU series are basically low-priced representatives, while Atom is Intel’s cheapest processor product line. The first two can only meet the basic functions such as browsing the web, editing simple document forms and watching videos, while the latter can only meet the lowest level of browsing the web and watching videos.

Celeron and Pentium CPU series are suitable for users who have a very tight budget and low performance requirements. These users may not rely much on notebooks, but they do need to use them for some work.

Celeron and Pentium series processors

The Atom series only appears on ultra-cheap laptops or tablets, which are suitable for children’s computer education, or as an auxiliary and expansion of the main notebook. Of course, their advantage is that they are cheap and have a long battery life.

Atom series processor

Mainstream models: Pentium N3700, Pentium 4405U, Celeron N3060, Celeron 3855U, Atom x7-Z8750, Atom x5-Z8500.

Introduction of some technical parameters of CPU

The main parameters of CPU processor are model, instruction set and architecture, frequency, number of cores/threads, etc. As for naming rules, we have talked clearly in the last article, so this article mainly analyzes the remaining parameters.

Instruction set and microarchitecture

CPU will follow certain specifications when performing computing tasks, and programs need to be translated into a language that CPU can understand before being executed. This specification or language is called instruction set.

The hardware architecture of CPU is called microarchitecture, and microarchitecture uses hardware circuits to realize instruction sets. Different microarchitecture designs will affect the working frequency of CPU core, as well as the computation and energy consumption level at a certain frequency. Therefore, although the main frequency of CPU has not been greatly improved in recent years, thanks to the improvement of micro-architecture and process upgrade, the computing power of CPU has also been greatly improved.

For ordinary users, you can choose an updated architecture with confidence. Usually, the computing power of the new architecture CPU will be stronger than that of the old architecture products with the same positioning (simply put, buy new products instead of old ones).

frequency

Under the premise of the same architecture, frequency is a very intuitive index to measure CPU performance. The reason why the concept of architecture is introduced is that many people who don’t know the truth like to judge the performance of CPU by its main frequency, but they don’t know that the main frequency can’t be directly used to compare the performance between CPUs under the premise of different microarchitectures.

The frequency of CPU has three parts: Clock Speed, frequency doubling and external frequency, and the main frequency is equal to the product of the latter two. Intel’s CPU also has a turbo frequency, which is actually an acceleration technology, but the CPU can’t work at the maximum turbo frequency for a long time.

For example, the main frequency (fundamental frequency) of Intel Core i5 7200U is 2.5GHz, and the maximum turbo frequency is 3.1GHz, which is the maximum working frequency, but it can’t run at 3.1GHz for a long time. Moreover, there is a temperature wall on the notebook, which will actively reduce the CPU working frequency when the temperature reaches a certain level, so we should choose the one with high basic frequency instead of the one with high maximum core frequency.

Number of cores/threads

CPU has two main parameters: core and thread, such as Intel Core i7-7820HQ, with 4 cores and 8 threads. Core refers to the physical core of CPU, while thread is the smallest unit of program execution flow. Through hyper-threading technology, one physical core can handle two threads at the same time, which further improves the running efficiency of CPU.

This year, the 8th generation Core i7-8650U, i7-8550U, i5-8350U and i5-8250U have all been upgraded to 4 cores and 8 threads, with better multi-tasking performance. It is recommended that daily office users who do not need games and professional applications choose the 8th generation Core.

TDP

Some netizens may mistake TDP for the actual power consumption of CPU or GPU, but this is not the case. TDP, that is, thermal design power, refers to the maximum heat generated by computer chips or components (usually CPU or GPU) dispersed by computer cooling system under typical workload.

TDP does not represent the actual power consumption of CPU/GPU, but it can estimate the calorific value of CPU according to TDP.

In addition, under the premise of the same performance, the lower the TDP is, the better. This parameter may not mean much to consumers. If you want to know the actual power consumption of CPU and GPU, you still need to go through actual tests to calculate it.

Summary: Determine the purpose and choose the strongest one within the budget.

Although there are many kinds of notebook CPU, the new products in recent two years are not so complicated. As long as you determine the good use, combine your own budget, and choose the product with the strongest performance according to the naming rules of CPU within the budget.

Contents and operation management of OBD inspection of vehicle inspection

In the field of modern automobile maintenance and inspection, OBD(On-Board Diagnostics) inspection has become a key technology, which can monitor the electronic control system of vehicles in real time and ensure the safety of vehicle operation and environmental protection standards. OBD inspection mainly involves the following aspects:

1. Reading and clearing fault codes

OBD system can record the fault information in the process of vehicle running and store it in the form of fault code. Technicians can read these fault codes by connecting the OBD interface of the vehicle with a special scanning tool, and then diagnose the problem. After the maintenance is completed, it is necessary to clear the fault code to ensure that the system returns to the normal monitoring state.

2. Real-time data flow monitoring

OBD system can also provide real-time data flow of vehicles, such as engine speed, vehicle speed and coolant temperature. These data are very important for diagnosing vehicle performance problems, and technicians can analyze these data to judge whether there is abnormality in the vehicle.

3. Emission testing

OBD system plays an important role in emission control. It can monitor the emission level of vehicles and ensure that they meet the requirements of environmental regulations. If excessive emissions are detected, the system will record relevant fault codes, prompting that maintenance is needed.

Operation and management

When carrying out OBD inspection, technicians need to follow the following operation procedures:

At the management level, in order to ensure the effectiveness of OBD inspection, maintenance enterprises need to regularly train technicians to update their knowledge and skills. At the same time, enterprises should also invest in advanced scanning tools and diagnostic equipment to improve the accuracy and efficiency of inspection. In addition, the establishment of a perfect OBD inspection record and tracking system will help enterprises to better manage vehicle maintenance and improve customer satisfaction.

In a word, OBD inspection is an indispensable part of modern automobile maintenance, which ensures the safety and environmental performance of vehicles through real-time monitoring and data analysis. Correct operation and management can help maintenance enterprises to provide higher quality services and meet increasingly stringent vehicle inspection requirements.

　　June 12th is the "Cultural and Natural Heritage Day" in 2021, and traditional cuisine is an important part of intangible cultural heritage.

　　In the latest list of the fifth batch of national non-legacy representative projects, Anhui cuisine cooking skills, Sichuan cuisine cooking skills, Liuzhou snail powder making skills and many other food items are among them.

　　The once hometown flavor has now become a collective memory.

　　More and more regional delicacies have been excavated, spread and protected.

　　"Dry rice people", look at the following things on the tip of your tongue. Do you often eat them?

　　Anhui cuisine: "heavy oil, heavy color and heavy fire power"

　　The old Huizhou cuisine "Mao Tofu" is on display in China Museum of Huizhou Cuisine. (photo by Shi Yalei)

　　Stinky mandarin fish, hairy tofu, steamed stone chicken … … These cuisines, which have been bred in Huizhou since ancient times, have already spread all over the country.

　　Huizhou cuisine is the general name of Huizhou cuisine. Its cooking skills were formed in the Northern Song Dynasty, became popular in the Southern Song Dynasty and became famous in the Qing Dynasty. It has been listed as a national intangible project in China.

　　Different from other cuisines, traditional Anhui cuisine is good at cooking, stewing and steaming, and it is heavy in oil, heavy in color and heavy in fire. According to the characteristics of dishes, we need to skillfully use different heat, such as mild fire, slow fire and strong fire, so that the cooked dishes are soft and waxy without losing their color and the stewed soup is mellow and fresh without losing its soul.

　　According to the relevant person in charge of the non-legacy office of Anhui Provincial Department of Culture and Tourism, Huizhou cuisine is widely distributed with the footprints of Huizhou merchants. In addition to Huizhou, Huizhou Cuisine Hall is also widely distributed in major cities in China.

　　Korean kimchi: an appetizer that combines "spicy, salty, sweet and sour"

　　Korean kimchi. (Information provided by Jilin Provincial Department of Culture and Tourism)

　　Kimchi is one of the most representative foods in the traditional diet of Korean people in China. Its production skills are listed as national intangible cultural heritage projects in China. Korean kimchi, in a broad sense, includes kimchi, small pickles and pickled pickles in sauce, among which the most common pickle is pickled with Chinese cabbage as the main material.

　　Pickling kimchi is not simply "kimchi+salt", but the selection of raw materials, salt treatment and seasoning preparation are all very particular. In ancient times, kimchi was pickled with salty salt or vinegar. In modern kimchi, spices such as pepper, garlic and ginger were added, so that kimchi, which was originally salty or sour, became spicy, salty, sweet and sour.

　　As a provincial-level non-legacy project in Anhui Province, Huainan beef soup has the characteristics of fresh alcohol, freshness and strong fragrance. You need to cook the soup with beef bones until the soup is clear and strong, and then add beef to the soup to cook. When the key soup heads are available, the store will put thin slices of beef, thousands of pieces, bean cakes and sweet potato powder on the table. After the guests arrive, the selected materials will be cooked in the pot, poured with fragrant and boiling soup, and added with some red oil, and a bowl of rich and delicious authentic beef soup will be completed.

　　Red oil is a hidden "mystery" in Huainan beef soup, which is made by frying red pepper in butter, so it is spicy and fragrant, and is deeply loved by diners.

　　Stewed sheep in Hengshan: a welcome dish with tender meat

　　Stewed sheep in Hengshan Mountain. source map

　　In Hengshan District, Yulin City, Shaanxi Province, hot stewed mutton is the main course for local people to welcome guests.

　　What is unique? It turns out that there are abundant plants such as ground pepper leaves, chives, flowers and plants, and there are clear and pollution-free natural springs, which are the best raw feed to improve the taste of mutton, so Hengshan mutton is famous for its tender meat.

　　For more than 1000 years, local people have explored and summarized a set of unique cooking techniques, including the procedures of selecting sheep, slaughtering sheep, stewing meat, etc. Among them, not only the quality of mutton should be excellent, the seasoning should be refined, but also the size of meat pieces and the ratio of meat to water when stewing meat have detailed requirements. This cooking technique has also been selected as a provincial-level non-legacy project in Shaanxi Province.

　　Huayang Ciba: A salty and spicy Ciba made of potatoes.

　　Huayang Baba source map

　　In the hinterland of Qinling Mountains in huayin city City, Shaanxi Province, due to the large temperature difference in the mountains and the long growth time of crops, the local people found that the potatoes produced here had high starch content and good taste, so they were used as raw materials for Ciba.

　　Talking about Huayang Ciba, I have to say that it’s a water dish. Slurry vegetables are made by pouring clear soup of cooked noodles or cooked thin batter into a pottery jar for fermentation, adding wild vegetables such as mustard, celery and radish tassel, and soaking in a sealed pottery jar.

　　Different from the sweet taste in other places, Huayang Ciba is famous for its salty and spicy taste of "sour, spicy and refreshing", which is poured with special slurry vegetables and then added with oily spicy seeds.

　　Milk fan: A "fan" made of milk can be salty and sweet.

　　Milk fan is a state-level non-legacy project in Dali Bai Autonomous Prefecture of Yunnan Province, which is made from fresh milk.

　　Different from ordinary fried milk rolls, its production process is exquisite. First, some milk is fermented into yogurt, which is heated to 70-80 degrees Celsius in a pot. Then, a certain amount of fresh milk is scooped into the pot, stirred slowly with a wooden spoon, and then taken out and kneaded until it condenses into a dough. Then, two thick wooden chopsticks are spread and rolled into thin slices in turn, and the two ends are pulled out, and the roll is wrapped on a bamboo fan rack to dry, which is roughly like a water chestnut-shaped bamboo fan.

　　Breastfans can be eaten in a variety of ways, such as dry, fried, roasted and boiled, salty or sweet. The most commonly used method is to fry vegetable oil and sprinkle salt or sugar to eat.

　　Chinese food culture is extensive and profound, and there are too many delicious foods waiting for you to taste. Although what you eat is taste, what you taste is culture.

CCTV News:Recently, anti-smuggling personnel of Xiamen Customs seized rhinoceros horn worth about 100 million yuan and weighing 250 kilograms. At present, there are only five species of rhinoceros left in the world, mainly distributed in Asia and Africa, among which Asian rhinoceros is on the verge of extinction.

A few days ago, Xiamen Customs Anti-smuggling Bureau received a clue that Wang from Wenzhou would go to Fujian to receive a batch of rhinoceros horns smuggled at sea.

Gao Lin, a policeman of Xiamen Customs Anti-smuggling Bureau:Normal ocean-going ships are at least 10,000 tons. The 1,600-ton cargo ship bought by smuggling gangs has changed hands several times, and the ship is in poor condition and has poor weather resistance, so it is easy to capsize in bad weather. In order to gain illegal benefits, smuggling gangs set out from Africa and smuggled directly to China without transit. This method is rare in the history of our case investigation, and it can be said that smuggling gangs are very crazy.

With the support of the marine police department, the suspicious ship was successfully seized and 11 suspects were arrested on the spot. The customs anti-smuggling police searched the ship and finally found that the paint color of an area in the engine room was not consistent with that of other places, which was suspected of repainting. After further inspection, it was confirmed that the smuggling gang had transformed the auxiliary oil warehouse in the engine room into a small warehouse, and 14 black luggage bags were hidden in it, all of which were rhinoceros horns. After counting, the customs anti-smuggling police seized 145 pieces of endangered species rhinoceros horn, including 110 whole horns and 35 pieces, weighing 250 kilograms.

The anti-smuggling police of Xiamen Customs found that this smuggling gang was not only bold, but also had a strong anti-investigation consciousness. The internal division of labor of the gang was very clear, the organization was tight, and the smuggling methods were very hidden.

In order to escape the attack of the customs, the smuggling gangs hired a large number of foreign crew members from Southeast Asia to drive smuggled ships, and registered the ships purchased at home as foreign ships.

Gao Lin, a policeman of Xiamen Customs Anti-smuggling Bureau:The internal division of labor of the gang is very clear and well organized, from organizing the supply of goods in Africa to smuggling at sea, then receiving the goods on the shore, and then selling the stolen goods at home, which is closely linked. Every link has a special person to be responsible and a single point of contact, which has caused great obstacles to our investigation. Moreover, the backbone members of this gang have rich experience in smuggling, and several of them are fugitives who have been chasing for a long time on the Internet. When we arrested one of the backbone members, Qiu Mou, he carried a number of mobile phones and more than 20 calling cards at home and abroad.

At present, the case has been handed over to the judicial department for handling.

According to the anti-smuggling personnel of Xiamen Customs, some African countries implanted chips in the horns of rhinoceroses to protect them and established rhinoceros identity systems. However, the anti-smuggling police of Xiamen Customs found that 70 pieces of rhinoceros horn seized this time contained chip information, which further confirmed that the smuggled goods came from Africa.

Of the rhinoceros horns seized, 110 were slightly damaged, which should be taken directly from the rhinoceros. The other 35 were cut from different rhinoceros horns according to their size and appearance, and about 100 rhinoceros were slaughtered.

The observation records of nova supernovae confirm the modern theory of stellar evolution

Apart from some scientific and technological inventions that can be easily and accurately classified and named, some of the 88 important inventions in ancient China need to be properly summarized. For example, "astronomical records" generally reflect the achievements of ancient astronomical observation in China. It is reported that China was good at astronomical calculations in ancient times, and accumulated a large number of systematic observation records, among which nova and supernova observation records also made important contributions to modern scientists’ research on high-energy celestial bodies such as supernovae, radio sources, pulsars and neutron stars.

According to reports, among the astronomical records in ancient China, the most valuable information is related to solar eclipses, comets, sunspots and new stars. The detail and accuracy of the records of comets, meteors and nova in history books enable modern people to accurately determine their position, brightness and movement change process according to these records, and many records are also of high application value to modern astronomical research.

Among them, the most prominent application of solar eclipse record is to study the change of earth’s rotation speed. The long-term change of the earth’s rotation can be obtained by comparing the modern calculated solar eclipse with the actual observation data of this solar eclipse in history. The reliable solar eclipse records in history mainly come from China. There are more than 1000 records of comets in the history of China, which were first recorded in Spring and Autumn Annals, and comets have been regarded as celestial bodies. In contrast, the West regarded comets as burning phenomena in the atmosphere from Aristotle until the 16th century.

From Shang Dynasty to the end of 17th century, China recorded more than 90 nova and supernova events, which is a very precious astronomical record in the world. In 1950s, Xi Zezong, a Chinese planetarium historian, compiled and published A New Table of Ancient Novas, which examined these records in detail, making a very important confirmation for the modern theory of stellar evolution, and was the most wonderful chapter in the application of ancient astronomical records in China.

Records of solar eclipse in Shangshu

In the Northern Song Dynasty, the water transport instrument was built with astronomical observation function.

Some inventions have not developed continuously, or their practical functions are limited, but they show extraordinary wisdom and skills, such as water transport instruments and platforms. The camera platform of water transport instrument integrates the functions of timing, astronomical demonstration and astronomical observation. The creator invented the ingenious "escapement mechanism" and expressed the mechanical structure with a complete set of drawings, showing Chinese’s superb level of designing complex mechanical systems.

The water transport instrument observatory is a large astronomical instrument system built in the Northern Song Dynasty, and it is an observatory integrating armillary sphere, elephant and timing device. Its creativity is mainly reflected in two aspects: firstly, the water wheel, gear train, control machine, timer, elephant and armillary sphere are integrated into a mechanical system, which reflects the high level of designing complex machinery; Secondly, it invented the control machine-Tianheng, which is composed of rod system and scale leakage, and its function is equivalent to the escapement mechanism of modern mechanical clocks and watches.

The water flowing evenly from the clepsydra is injected into the bucket of the water wheel to drive the water wheel to rotate. Under the control of the mechanism composed of rod system and scale leakage, the water wheel rotates evenly and intermittently. Through the gear train and even the chain drive, the water wheel simultaneously drives the timing device, demonstrates the elephant of the sky and observes the armillary sphere of the starry sky. The timing device rings the bell, rings the bell, shows the cards, beats the bell and drums to tell the time, engrave and watch the shift. The armillary sphere is mainly composed of triple rings, and its inner "four-travel instrument" has a watchtube. The water wheel drives the "four-swimming instrument" to run with the sky, which can make the telescope rotate with the starry sky target. This design is the prototype of the rotating clock in later generations.

Double Stirrups Unearthed from the Tomb of Beiyan Feng Sufu

Stirrups appeared in the Eastern Han Dynasty, which seems to be of great military significance.

In contrast, some inventions are not prominent in the complexity of technology, but they have had a great impact on the process of civilization. For example, although the stirrup is simple in structure, it has significantly improved the combat effectiveness of cavalry.

Stirrup is a stepping and supporting device when riding a horse, which is usually similar to a semi-elliptical ring. The stirrup ring is made of leather, iron and other materials with high strength, and the lower edge can be made of wood or rattan, and the iron or leather is wrapped outside to make wider pedals, which usually hang under the saddle in pairs. When getting on the horse, the rider can step on the back of the horse with one stirrup. When riding, your feet pass through the stirrup to help stabilize your body. When galloping, the rider stands on the stirrup with the stirrup as the main support point, and the upper body leans forward, which makes the rider’s hands more free and can move left and right on horseback.

According to textual research, in the Eastern Han Dynasty, China had a single stirrup hanging on the left side of the horse to assist in getting on the horse. The double stirrup matched with a terracotta horse figurine in the tomb of Wang Kui in Xiangshan, Nanjing is the earliest discovered material, which should appear no later than the beginning of the 4th century.

After the invention, stirrup soon spread to Koguryo area in Northeast Asia, and spread to the west through nomadic grassland people such as Turks. From the end of the 6th century to the beginning of the 7th century, Sassanian Persians introduced stirrups from Turks, and passed this technology on to Arabs in the 7th century. In the early 7th century, Avar brought the stirrup to Eastern Europe and Byzantium, and gradually spread to Northern Europe and Western Europe.
Stirrup is of revolutionary significance in military history. It enables knights to give full play to their weapon effectiveness in combat, thus further promoting the development of heavy cavalry. Therefore, this is a seemingly small but historically significant invention.

The contribution of the four major crops cultivation is not inferior to the "four great inventions"

Throughout ancient history, some scientific and technological knowledge may have originated from many places. However, more and more complicated scientific and technological knowledge may be shared by different civilizations through communication. For example, Chinese has contributed to the world the cultivation methods of crops such as rice, soybeans and tea, as well as the technologies of silk weaving, porcelain, paper making, printing, gunpowder and compass, and also introduced crops such as wheat, cotton, corn, potatoes and tomatoes.

In fact, the scientific and technological creativity of the Chinese nation has not yet been fully understood by the public. Our ancestors first cultivated the most important food crop-rice, the most important bean crop-soybean, one of the most important fruit crops-citrus, one of the three beverage crops-tea. The spread of these crop cultivation techniques is not inferior to the "four great inventions" in their contribution to human survival and development.

For example, rice cultivation has made rice the world’s largest food crop, and more than half of the world’s population lives on rice. According to reports, China, India and Southeast Asia may all be the earliest domestication centers of rice, but China’s view as the origin of cultivated rice in Asia has been supported by more and more archaeological evidence. There are 167 places where prehistoric cultivated rice remains in China have been unearthed, and there are four places with a time of more than 10,000 years. Among them, rice remains dating back about 12,000 years have been found in Xianrendong site and Diaotonghuan site in Jiangxi province, and the earliest rice specimens in the world have also been unearthed in Yuchanyan site in Daoxian county, Hunan province. All these provide further evidence for the statement that China is the origin of cultivated rice in Asia.
