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 Wonton" in the Three Kingdoms period, "Wonton" in the Northern and Southern Dynasties, "Crescent Wonton" in the Tang Dynasty, "jiaozi" in the Song Dynasty and "Flat Food" in the Ming and Yuan Dynasties. The Qing Dynasty called it "Jiaozi". Jiaozi originated in the Eastern Han Dynasty and was initiated by Zhang Zhongjing, a doctor in Nanyang, Henan Province in the Eastern Han Dynasty. 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 is characterized by its thin skin and tender stuffing, delicious taste and unique shape, which makes people have an appetite. Jiaozi's raw materials are rich in nutrition, and the cooking method ensures less loss of nutrients, which conforms to the connotation of China's color, fragrance and food culture. 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.
