The discovery of ancient human fossils in Wuguidong site in Hangzhou proves that ancient humans lived in this land 50 thousand years ago. Hangzhou belongs to Baiyue before summer, and Xia, Shang and Zhou belong to "Yangzhou territory". 2 1 century BC, Yu Xia made a southern tour and was the governor of Huiji (now Shaoxing). He sailed through here and left his boat here ("Hangzhou" is the ark), hence the name "Yuhang". It is said that Yu built a boat to cross here, and the Vietnamese call it "Yuhang". Later, according to oral tradition, Yu was called "Yu" and named "Yuhang". After the establishment of the Sui Dynasty, in the ninth year (589), the county was abolished as a state, and the name "Hangzhou" first appeared.
