Chen Wu
Chen Biao was a son of Chen Wu, a general who served under the warlord Sun Quan in the late Eastern Han dynasty. He was born to Chen Wu's concubine and was a younger half-brother of Chen Xiu (陳脩), who was born to Chen Wu's official spouse. Chen Wu was killed in action in 215 at the Battle of Xiaoyao Ford, while Chen Xiu died in 229, shortly after Sun Quan proclaimed himself emperor and established the state of Eastern Wu.
