 As Empress Shen and Chen Yin often exchanged messengers, Chen Shubao suspected that Chen Yin despised him for not favoring Empress Shen.Consorts Zhang and Kong, assisted by the high-level official Kong Fan (孔範, who, although he was not related to Consort Kong, referred to her as his sister), began to make accusations against Chen Yin before Chen Shubao.In 588, Chen Shubao thus decided to depose Chen Yin and make Consort Zhang's son Chen Yuan the Prince of Shi'an crown prince, despite Yuan's opposition.
