Chopsticks, with a history of thousands of years, are unique traditional Chinese dining utensils. They were called "zhu" in ancient China and the name of "Kuai Zi" began to be used in Ming Dynasty. Chopsticks are usually made of bamboo. Some are made of wood, ivory, metals or other materials. Their upper parts are square and lower parts round, or they are all round with thicker upper parts and thinner lower parts. Whatever their shapes are, they are used in pairs and the pair must be identical to each other. chopsticks are the necessary dining utensils in Chinese people's daily life, the invention of which fully delays the intelligence of Chinese people.
