Introduction to Chengniang Bridge: Chengniang Bridge was originally called Chengliang Bridge and can be traced back to the Yongle period of the Ming Dynasty. It is said that there was a family named Yang beside the bridge. His father died young and his two sons grew up and started separate families. The elder brother lived on the east side of the bridge and the younger brother lived on the west side of the bridge. The two brothers were both dutiful sons, competing to respect and support their mother. They made a contract: they would take turns caring for my mother for a month, and every first day of the new year, they would pick her up and see her off on the bridge in front of their house, and in front of all the neighbors. Next, weigh me to see if the mother is serious or not, and let the neighbors judge whether the son is ugly or not. Over and over again, the old lady took care of herself until she was old enough, living in the same house for four generations, until she was over ninety years old and died without any illness. In order to praise the virtues of their brothers, people renamed "Chengliang Bridge" as "Jiang Niang Bridge".
