Chen Shubao
Emperor Xuan died in 582, and Chen Shubao, after surviving a coup attempt, became emperor. He created Chen Yin crown prince, and in 583 created many of his sons, including Chen Yuan, imperial princes (in Chen Yuan's case, the Prince of Shi'an). Chen Yuan was said to be composed and intelligent in his youth, and not even his attendants could tell his emotions easily. In 588, Chen Shubao, after believing in accusations against Chen Yin, deposed Chen Yin and created Chen Yuan crown prince instead.
