Chen Shubao
Chen Yin was the first son of his father Chen Shubao, who was crown prince under Chen Yin's grandfather Emperor Xuan at the time of Chen Yin's birth. Chen Yin's mother Consort Sun died in childbirth, and Chen Shubao's wife Crown Princess Shen Wuhua, mournful of her death, took Chen Yin and raised him as her own son. As Chen Shubao was already 20 at the time of Chen Yin's birth—a relatively late age to have a son in those times—Emperor Xuan had Chen Shubao designate Chen Yin as his heir even though Chen Yin was not born of Crown Princess Shen, and further awarded a bowl of wine to each father in the realm. In 578, he was created the Duke of Yongkang.
