Zheng Zhu
There was, at the time, a rumor spread in Chang'an that Zheng Zhu was making immortality pills for Emperor Wenzong, and that the pills required infant hearts and livers as ingredients, causing much panic among the people. Zheng accused family members of the mayor of Jingzhao Municipality (京兆, i.e., the Chang'an region) Yang Yuqing (楊虞卿) of spreading the rumors, and Emperor Wenzong, incensed, arrested Yang. When Li Zongmin, who had previously refused to give Zheng an office he wanted, tried to intercede on Yang's behalf, Emperor Wenzong ordered Li Zongmin to leave his presence, and soon had him exiled.
