The following is an introduction to Miss Dumplings:
Jiaozi evolved from wonton. In its long development process, there are many names, such as "prison pill", "flat food", "dumpling bait" and "powder horn" in ancient times. It was called "Crescent Moon Wonton" in the Three Kingdoms period, "Wonton" in the Southern and Northern Dynasties, "Crescent Moon Wonton" in the Tang Dynasty, "Jiao Zi" in the Song Dynasty and "Flat Food" in the Yuan and Ming Dynasties. In Qing Dynasty, it was called "jiaozi".
Jiaozi originated in the Eastern Han Dynasty and was first created by Zhang Zhongjing, a native of Dengzhou, Henan Province in the Eastern Han Dynasty. At that time, jiaozi was used for medicine, and Zhang Zhongjing wrapped some cold-dispelling herbs in dough to treat diseases (mutton, pepper, etc.) to avoid frostbite on patients' ears.
Jiaozi is a folk food in China with a long history, and eating jiaozi is also a unique folk tradition of Chinese people during the Spring Festival. Because it means "making friends at a younger age", it is very popular among the people. During the Spring Festival, jiaozi has become an indispensable delicacy.
