Origin
According to legend, Ruomu was one of the two sons of Boyi. Boyi successfully assisted Yu the Great with resolving the Flood, so the King conferred one of the eight noble tribal names, Yíng, to the family of Boyi; and simultaneously Ruomu was appointed as the King of the land of Xú. This was the beginning of the establishment of the state Xú. The state has been reigned over by the royal family for more than a thousand years, and had 44 monarchs.

The state of Xú was eliminated by the state of Wú, since then in order to commemorate their ancestral pride, descendants of King Ruo'mu adopted their country's name, Xú, as their surname. Therefore, the surname, Xú, is originated from King Ruo'mu, and it belongs to the noble tribe of Yíng.

Jiangsu is the province with the highest concentration of the surname Xu.
