Jiaozi, also known as dumplings, formerly known as Jiaoer, is an ancient traditional pasta in China, which originated from Wancheng in the Central Plains and has a history of more than 1,800 years. Jiaozi is deeply loved by the broad masses of people in China. It is a must-eat food in most parts of northern China during the Spring Festival every year. In many provinces and cities, it is also a habit to eat jiaozi on the Winter Solstice Festival.
Jiaozi was invented by Zhang Zhongjing, a doctor in Nanyang, China in the Eastern Han Dynasty. Its historical evolution has gone through a long process. At the end of the Ming Dynasty, Zhang Zilie made a good explanation: "Dumpling ears, that is, Duan Chengshi food, soup pills, or powder horns, are pronounced jiao by northerners, and they are fake dumplings because they call dumplings bait." When wrapping jiaozi, people often wrap Jin Ruyi, sugar, peanuts, dates and chestnuts into stuffing. Those who eat the best and sugar will have a sweeter life in the coming year, those who eat peanuts will live a long and healthy life, and those who eat dates and chestnuts will have a baby early. In some areas, when people eat jiaozi, they have to match some non-staple food to show their good luck. For example, eating tofu symbolizes the happiness of the whole family; Eating persimmon symbolizes all the best; Eating three fresh vegetables symbolizes the prosperity of three yang. In some places in the south, eggs will be broken up during the Spring Festival, and then heated to make a crust and wrapped with meat stuffing, which is called egg dumplings.
