Dumpling, formerly known as jiao'er, was invented by Zhang Zhongjing, a famous physician in the Eastern Han Dynasty. At that time, dumpling was used as a medicine to treat diseases. In the last years of the Eastern Han Dynasty, there were frequent wars and epidemics. People lived hard. In winter, they lacked warm clothes. When they went out to work in agriculture, the wind was cold and their ears were often frostbitten. To solve this problem, Zhang Zhongjing created the rudiment of dumplings. He added cold repellent drugs to the thin noodle skin, cooked it in hot water and fed it to the people, which could not only solve the problem of food and clothing, but also drive the people away Cold and warm, gradually, this method spread among the people. After continuous development, people gradually found that some ingredients, such as beef, mutton and mutton, could be put in the dumplings. This was the dumplings eaten by the rich people at that time, while the poor people could only put some vegetables and minced meat in the dumplings.
