Cao Ziqin

Cao Ziqin (birth and death dates unknown) was a son of Cao Cao, a warlord who rose to power in the late Eastern Han dynasty and laid the foundation for the state of Cao Wei in the Three Kingdoms period of China. His mother was Lady Sun (孫姬), a concubine of Cao Cao. She also bore Cao Cao two other sons: Cao Zishang and Cao Biao. Cao Ziqin died early and had no son to succeed him. He was posthumously honoured as "Duke Shang of Gang" (剛殤公) in 231 by Cao Rui, the second emperor of the Cao Wei state.
