By spring 840, Emperor Wenzong was seriously ill. He had his trusted eunuchs Liu Hongyi (劉弘逸) and Xue Jileng (薛季稜) summon the chancellors Li Jue and Yang Sifu to the palace, intending to entrust Li Chengmei to them. However, the powerful eunuchs Qiu Shiliang and Yu Hongzhi (魚弘志), who controlled the palace by that point, opposed Li Chengmei because they were not consulted before Emperor Wenzong created Li Chengmei crown prince. Despite Li Jue's opposition, they issued an edict in Emperor Wenzong's name demoting Li Chengmei back to Prince of Chen (under the excuse that Li Chengmei was too young) and creating another brother of Emperor Wenzong's, Li Chan the Prince of Ying crown prince. Emperor Wenzong soon died, and after Emperor Wenzong's death, Chou persuaded Li Chan to order Li Chengmei, as well as Consort Yang and Li Rong, to commit suicide. Despite Li Chengmei's relative young age, he had at least 19 sons, and his 19th son, Li Yan (李儼), was later created an imperial prince.
