劉拠
One of the conspirators against Crown Prince Ju was Jiang Chong (江充), the ruthless and opportunistic head of the secret intelligence, who once had a run-in with Prince Ju after arresting one of Prince Ju's assistants for improper use of an imperial right of way. Fearing that with Emperor Wu's health declining, Crown Prince Ju would one day ascend to the throne and punish him for their past clashes, Jiang Chong decided that he had to remove the Crown Prince once and for all. One other conspirator was Emperor Wu's chief eunuch Su Wen (蘇文), who had falsely and repeatedly accused Liu Ju of committing adultery with Emperor Wu's junior concubines. Su Wen also blocked any attempts by Liu Ju and Empress Wei to communicate with Emperor Wu, who was then staying at his summer palace in Ganquan (甘泉, in modern Xianyang, Shaanxi).
