The Chinese surname (simplified: ; ) is listed 49th in the Song dynasty classic text Hundred Family Surnames. As of 2008, is the 115th most common surname in China.

Origin According to several ancient genealogy texts including the Tang dynasty Yuanhe Xing Zuan, Xing Pu (), and Xingshi Kaolue (), the surname originated from the ancient State of Lu, which was founded by Bo Qin, son of the Duke of Zhou, during the 11th century BC. During the Warring States period, Lu was conquered in 256 BC by the state of Chu, one of seven major powers of the period. Many of Lu's people subsequently adopted the name of their former state as a surname. It is considered a derivative of Ji (), the royal surname of the Zhou royal family.
