2. jiaozi is a folk food with a long history and is deeply loved by people. There is a folk saying "delicious but not as good as jiaozi". During the Spring Festival, jiaozi has become an indispensable delicacy.

3. According to "Guangya" written by wei ren Zhang Yi in the Three Kingdoms Period, there was a crescent-shaped food called "Wonton" at that time, which was basically similar to the shape of jiaozi now. By the time of the Northern and Southern Dynasties, wonton had been "shaped like a crescent moon, and it was delicious all over the world".

Presumably, when he was a jiaozi, he didn't fish out jiaozi and eat it alone, but mixed it with soup, so people called jiaozi "wonton" at that time. This way of eating is still popular in some areas of our country. For example, when people from Henan and Shaanxi eat jiaozi, they should put some small ingredients such as coriander, chopped green onion, shrimp skin and leek in the soup.

By the time of Tang Dynasty, jiaozi had become exactly like jiaozi now, so it was fished out and eaten on a plate alone.

Jiaozi was called "Joule" in Song Dynasty, which was the etymology of the word "Jiaozi" in later generations. This kind of writing can still be seen in the following Yuan, Ming, Qing and Republic of China.
