The Origin of Zhang's "Cockcrow"

Zhang's crow comes from a legend about the origin of ancient surnames in China. According to the records in ancient books such as Textual Research on Surnames and Genealogy, the ancestor of Wang was the doctor of Qi in the Spring and Autumn Period and was appointed as the Prime Minister of Lu. During his reign, he made important contributions to the politics, economy, culture and military of Lu. He also got the title of "cock crow". After Zhang Zi's death, his descendants took the place where he lived as their surname and called it Zhang Jiming to show their memory and respect for him.
