Prince Xian of Hengyang

Chen Chang (陳昌), courtesy name Jingye (敬業), formally Prince Xian of Hengyang (衡陽獻王), was an imperial prince of the Chinese Chen dynasty. He was the sixth and only surviving son of the founding emperor Emperor Wu, but as he was detained as a hostage by Western Wei and Western Wei's successor state Northern Zhou, was unable to succeed to the throne when Emperor Wu died in 559. Rather, his cousin Chen Qian took the throne as Emperor Wen. Northern Zhou finally allowed him to return to Chen in 560, but as he wrote impolite letters to Emperor Wen, Emperor Wen felt threatened, and he sent his trusted general Hou Andu to escort Chen Chang. Hou subsequently drowned Chen Chang in the Yangtze River.
