The Han dynasty basically inherited the system of the Qin dynasty, including the judicial system, so there is a saying in history that "Han inherited the Qin system." The central judicial organ of the Han Dynasty was Ting Wei, and the place was the same as that of the Qin Dynasty. However, after Emperor Wu of the Han Dynasty, the kingship was gradually strengthened, and a central organization, Shangshutai, appeared. Shangshutai has set up law enforcement agencies. There were three Cao Cao in the Western Han Dynasty and two thousand stone Cao in the Eastern Han Dynasty. Thus encroaching on the judicial power of Tingwei. In addition, in the Han Dynasty, major cases were jointly tried by central officials. This system of joint hearing, known as "miscellaneous office", reflects that the imperial power has further strengthened its control over judicial power.
