Yu is an ancient surname in China. The ancestors of the surname were closely linked with ancient sage-king of Yu Shun.
When Yu Shun was getting old, he took his initiative to hand over the state power to Xia Yu. And Xia Yu made his son Shang Jun the duke of Yu (it is now in Yucheng, Henan Province) with the founding of Yu kingdom. Later, the descendents of Shang Jun began to take the kingdom as their surname, according to the overseas edition of People��s Daily on Thursday.
Another Yu family was originated from surname Ji. According to history records, Zhou Wu Wang (1,134-1,115BC) overthrown the Shang Dynasty and made many dukes. He made later generations of his second uncle Zhong Yong the Yu kingdom (now in the northeast of Pinglu in Shanxi). Afterwards, the descendents of Zhong Yong bear the name of the kingdom as their surname.
After the surname coming into being, Yu people lived in Kaifeng and Chenliu areas in Henan for a long period of time, becoming big families. After Tang (618-907AD) and Song (960-1127 AD) dynasties, Yu families started to move to Huiji (now in Shaoxing, Zhejiang Province).
