Jiaozi, also known as jiaozi, is a traditional noodle of the Han nationality. It evolved from wonton, originated in the ancient corner of China, and was originally named "Jiaoer", with a history of over 1800 years.
It was invented by Zhang Zhongjing, a native of Nieyang (now Dengzhou, Nanyang, Henan) in the Eastern Han Dynasty, and was originally used as medicine. Deeply loved by the people of China, it is the staple food of the people in northern China, the local snack and the food for the New Year. There is a folk proverb called "freezing in the cold, eating jiaozi in the New Year." Jiaozi often cooks with flour and leather bag stuffing.
