Hangzhou Dialect before the Eastern Jin Dynasty

During the Spring and Autumn Period, wuyue competed with China for hegemony, and Hangzhou was first returned to the State of Yue, then to the State of Wu, and then to the State of Yue after the demise of Wu. Therefore, Hangzhou dialect at that time belonged to the ancient Wu dialect. Wu dialect was gradually merged with the language of the local non-Han Yue people when Tai Bo, King of Wu, moved to Wu in the Zhou Dynasty. Hangzhou dialect did not change on a large scale during the Qin and Han Dynasties and the Western Jin Dynasty. It was not until Yongjia Du Nan in the Eastern Jin Dynasty that Hangzhou dialect began to change for the first time.
