What is jiaozi and who invented it?

The earliest invention period: Eastern Han Dynasty, and the earliest inventor: Zhang Zhongjing.

jiaozi has a long development journey. Because jiaozi and wonton have a high degree of similarity, the first wonton appeared in the Three Kingdoms period.

But it was later called Wonton for short in the Northern and Southern Dynasties, renamed Jiaozi in the Song Dynasty, and evolved into what we call jiaozi in the Qing Dynasty.

What I'm going to tell next is not a fairy tale, but a true story. According to legend, at the end of the Eastern Han Dynasty, Zhang Zhongjing, as a medical sage, served as a satrap in Changsha, specializing in removing some bad diseases for the people. When he returned to his hometown, he saw that some poor people's ears began to freeze in winter, so he was very distressed and felt that he was incompetent as an immortal.
