Chopsticks Chopsticks are a great invention of China people. It is said that there are three ways to eat in the world, and 40% of them are eaten directly with their hands; 30% of them use chopsticks and 30% use knives and forks. China began to use chopsticks as early as Shang Dynasty, but it was not called "chopsticks" at first. In pre-Qin literature, the author called chopsticks "Zhu". In the Sui Dynasty, chopsticks were also called "tendons". How did the name "chopsticks" come from? According to Lu Rong in the Ming Dynasty, Wuzhong in the south of the Yangtze River is called "walking" and "fast". Canvas is called "rags" because boatmen are taboo about "living" and "turning". About after the Ming Dynasty, a bamboo head was added to the word "chopsticks", which became "chopsticks". This is probably because chopsticks are mostly made of bamboo. The structure of chopsticks is very simple. Chopsticks in our country are thick on the top and thin on the bottom ring. When chopsticks were introduced to Japan, the Japanese made them into cones. Although chopsticks are simple, people in China have made many articles on the quality and carving of chopsticks. There were ivory chopsticks and copper chopsticks in the pre-Qin period. Since the Sui and Tang Dynasties, palaces, yamen and rich families have made chopsticks with gold and silver, and carved chopsticks with jade and coral. Exquisite chopsticks also have silver heads to test whether food is poisonous or not. If it is poisonous, the silver head will turn black or green immediately. China people's kung fu with chopsticks often attracts foreigners. In recent years, there has been a "chopstick fever" in the West. There are also "training centers" that teach people to use chopsticks. Some medical scientists believe that using chopsticks can drive more than 30 joints and 50 muscles of human body, which is helpful to the dexterity of hands and the development of brain. It is also said that China's skillful hands have a lot to do with his ability to use chopsticks since he was a child. It is said that the world's first "Chopsticks Museum" is in Germany.
