The Song Clan of Jingzhao: Descendants of Weizi
Main line: descended from the Zi surname. Weizi Qi, elder half-brother of King Zhou of Shang, was enfeoffed by the Zhou with the State of Song (Shangqiu, Henan); when the state fell, descendants took the state name as their surname.
Multiple origins: branches from surname changes by ethnic minorities.
Root point: the ancient State of Song in Shangqiu, Henan.
▸ Domestic migration: rose in eastern Henan; crossed south to Jiangnan in the Wei–Jin era; entered Fujian and Guangdong in the Tang and Song; in the Ming and Qing, the Hongtong migrations and the exodus to Manchuria.
▸ Overseas branch: the Song of Minnan and Chaoshan went to Nanyang in successive waves.
