Chinese compound surname

A Chinese compound surname (literally "double surname") is a using more than one character. Many of these surnames derive from noble and official titles, professions, and place names. Some are originally non-Chinese, while others were created by joining two one-character family names. Only a few of these names (e.g. Ouyang, Shangguan, Sima, Situ) survive in modern times. Many clans eventually took on a single-character surname for various reasons. A small minority of Koreans and Vietnamese also have compound surnames.
