Jiaozi is a traditional food in China. Jiaozi originated from the ancient trough. Jiaozi, formerly known as Joule, was invented by Zhang Zhongjing, a doctor in Nanyang, China, with a history of 1800 years.

Jiaozi, also known as jiaozi, is a traditional special food deeply loved by the people of China. It is China's staple food and local snacks, and it is also New Year's food. There is a folk song called "A slight cold arrives, eat jiaozi in the New Year." Jiaozi often cooks with flour and leather bag stuffing.

The development of jiaozi

By the Northern and Southern Dynasties, wonton had been "shaped like a crescent moon, and it was delicious all over the world". Presumably, jiaozi didn't take it out and eat it alone when cooking, but put it in a bowl with the soup, so people called jiaozi "wonton" at that time. This way of eating is still very popular in some areas of China. For example, people in Henan and Shaanxi eat jiaozi, so they should put some small ingredients in the soup, such as coriander, chopped green onion, shrimp skin and leek.

Around the Tang Dynasty, jiaozi was fished out and put on a plate to eat alone, almost like jiaozi today. Also known as "Crescent Moon Wonton". There is a folklore in Chang 'an that a generation of empress Wu Zetian invented jiaozi.

Jiaozi was called "Joule" in Song Dynasty, which is the etymology of the word "Jiaozi" in later generations. Song Mengyuan's Dream of Tokyo recalls the prosperity of Bianjing in the Northern Song Dynasty. The second volume mentions that there are "Crystal Corner", "Frying Corner" and "Hump Corner" in the market.

Song Sishui's "Old Wulin Stories" mentioned in Volume 6 that there are "city corners" and "various corners" in Lin 'an market. This kind of writing can still be seen in the following Yuan, Ming, Qing and Republic of China. In the Southern Song Dynasty, it was called "dried meat with double horns".

Jiaozi was introduced to Mongolia in the Song Dynasty. Jiaozi spread to Mongolia, and jiaozi's pronunciation in Mongolian is similar to "plaque food". With the conquest of the Mongolian empire, flat food also spread to all parts of the world. There are many varieties such as Russian jiaozi, Kazakh jiaozi and Korean jiaozi.
