Jiaozi, also known as Dumpling, is a traditional noodle of Han nationality. It evolved from wonton, originated from the ancient corner of China, formerly known as "Jiao 'er", with a history of more than 1,800 years.
It was invented by Zhang Zhongjing, a native of Nieyang, Nanyang (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 snacks, and also the food for the New Year. There is a folk proverb called "It's cold and mild, eat jiaozi for the New Year." Jiaozi is often boiled with flour and leather bag stuffing.
