仇士良
In spring 840, Emperor Wenzong became seriously ill. He summoned Liu Hongyi and another eunuch, Xue Jileng (薛季稜), and asked them to summon Yang Sifu and Li Jue to the palace, ready to entrust Li Chengmei to them. However, the eunuch army commanders Qiu Shiliang and Yu Hongzhi (魚弘志), hoping to receive credit for supporting a new emperor, opposed Li Chengmei, arguing that Li Chengmei was too young and too sickly. Li Jue tried to stop them, but Qiu and Yu went ahead and issued an edict in Emperor Wenzong's name demoting Li Chengmei back to the Prince of Chen and creating Li Chan crown prince instead. After Emperor Wenzong soon died, Qiu persuaded Li Chan, who had not yet taken the throne and was still using his title of crown prince, to order Consort Yang, Li Rong, and Li Chengmei to commit suicide.
