In northern China, there is a custom of eating jiaozi in beginning of winter. First of all, beginning of winter will improve the life of this day, but "it's delicious, but it's not jiaozi"; Secondly, sexual intercourse comes from the saying that beginning of winter is at the turn of autumn and winter, so you can't help eating sexual intercourse.

Jiaozi (jiaozi) originated from the ancient corner of China, formerly known as Jiaoer, a traditional noodle of Han nationality. It has a history of 1800 years. It was invented by Zhang Zhongjing, a native of Nanyang (now Dengzhou, Nanyang, Henan) in the Eastern Han Dynasty. Initially, it was used as medicine, and jiaozi, also known as jiaozi, was deeply loved by the people of China. It is the staple food and local snacks in northern China, and it is also a holiday food.

Characteristics of jiaozi

1, jiaozi has stuffing, similar to steamed bread stuffing, which can be fish, vegetables, sugar stuffing, etc. This is different from wonton, which generally does not use sugar stuffing.

2. Dumpling skins are usually made of flour mixed with other grain flour, while wonton skins are mostly made of flour or a small amount of bean flour. In the Ming Dynasty, Gao Lian wrote "Eight Records of Respect for Life, Volume 13, Drinking and Eating", and the water bright angle method used flour and bean flour, and the wonton mainly used flour. Yuan Hui's "Eating while Eating Right" Volume 1, in which the crystal horn is made of bean powder, while the left horn and the left horn are made of flour.

3. Shut up after jiaozi is wrapped. This is the same as wonton. Vae's "Zhu Yu Shan Ju Miscellaneous Department" in the Ming Dynasty pointed out that wonton should be thinly cut into small square pieces with stuffing inside, obliquely folded into a pocket, and sealed at its tip, revealing a neat appearance. The square piece says it is very similar to the shape of wonton skin now. In addition, the soup corner should be filled and the pastry corner should be sealed.
