Why is Jiaxing named Jiaxing?

Jiaxing: It was once called "Xiuzhou". It turns out this place is called Youquan County. In the third year of Wu Huanglong's reign (231), "Fun wild rice grew on its own". Emperor Sun Quan of Wu thought it was an auspicious sign, so he changed the name of Quan County to Hexing County, and changed the reign name to Jiahe the following year. The change of the place name also reflects the Wu State's founding policy of "focusing on farming and grain farming" and the county's status in the Wu State. In the fifth year of Chiwu (242), Sun Quan made his son He the prince. He and He had the same pronunciation, so to avoid taboo, Hexing was changed to Jiaxing, and the name Jiaxing began.
