1, the crossover originated from the ancient trough. Jiaozi, whose original name was Joule, was invented by Zhang Zhongjing, a medical sage, and has a history of 1800 years. At that time, jiaozi was used as a medicine, and Zhang Zhongjing wrapped some cold-dispelling herbs in dough to treat diseases (mutton, pepper, etc. ) to avoid frostbite of patients' ears. Jiaozi, also called dumplings, is a must-eat food in China in the New Year. There's a saying, "It's cold and warm, so we eat jiaozi during the New Year.

2. jiaozi originally evolved from wonton. In the process of evolution, the names have been changing, such as "prison pill", "flat food", "dumpling bait" and "powder horn". During the Three Kingdoms period, jiaozi has developed into a kind of food. According to "Guangya" written by Zhang Yi, wei ren of the Three Kingdoms, there was a kind of food called "Wonton" at that time, which was crescent-shaped and basically similar to jiaozi, and was called "Crescent Wonton".

3. During the Northern and Southern Dynasties, wonton was "shaped like a crescent moon, and it was delicious in the world". Because jiaozi didn't eat outside at that time, he ate it with soup, so people called jiaozi "Wonton". Today, this way of eating is still popular. When people in Henan eat jiaozi, they like to put some coriander, chopped green onion, shrimp skin, leek and vinegar in the soup, which is called sour soup jiaozi.

6. In the Tang Dynasty, jiaozi was just like jiaozi now, although it was fished out and put on a plate to eat one by one. But they call it "Crescent Wonton".

7. It was only in the Song Dynasty that jiaozi was called "Jiao". In Song Dynasty, Yuan Meng mentioned "Crystal Corner", "Fried Corner" and "Hump Corner" when recording the prosperity of Bianjing. There is also the Old Wulin Story of the Song Dynasty, which mentions 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. It was also called "double-horned dried meat" in the Southern Song Dynasty. In the Song Dynasty, Jiaozi was introduced to Mongolia. In Mongolian, the pronunciation of jiaozi is similar to that of "Bian Shi". Flat food also spread to all parts of the world with the imperial expedition. Jiaozi, jiaozi, jiaozi and so on.

In the Ming Dynasty, the custom of eating jiaozi appeared during the Spring Festival. According to the Records of Meditation, the court session of the Ming Dynasty began on the 15th day of the first month ... drinking liquor and eating snacks (that is, jiaozi). Or there is a dollar or two hidden in it, and those who get it will get a one-year-old blessing, and they will also pay New Year greetings to each other on this day, which is called Happy New Year. "

9. In the Qing Dynasty, jiaozi became a must-eat food for the New Year. Generally, it should be wrapped before midnight on Lunar New Year's Eve and eaten at midnight. At this time, it is the beginning of the first day of the first lunar month. Eating jiaozi means "making friends when I was young", and "making friends" is homophonic with "jiaozi", meaning "happy reunion" and "good luck". This shows that people eat jiaozi in the Spring Festival, which means good luck, to show that they will bid farewell to the old and welcome the new.
