Wang Shuwen
Late in 805, Emperor Shunzong yielded the throne to Li Chun (as Emperor Xianzong). Wang Shuwen and his associates were immediately purged from government and exiled. In Cheng Yi's case, he was first made the prefect of Yue Prefecture (岳州, in modern Yueyang, Hunan), and then further demoted to be the military advisor to the prefect of Chen Prefecture (郴州, in modern Chenzhou, Hunan).
