Until 1979, China had never been a country with a highly differentiated legal system. From the Law Classics (Fa jing) in the Warring State period (480–221 b.c.) to the Great Qing Criminal Code (Da Qing lü li, effective during 1740–1910), the two-millennium history of codification in imperial China had always been characterized by a strong emphasis on criminal law; most noncriminal disputes were adjudicated according to the Confucian ethics (li) and social customs, without referring to any legal code. Meanwhile, in the Chinese political system there was no separate judiciary from the government, and the local magistrate was both the administrative leader and the judge for crimes and social disputes. Accordingly, no formal legal profession was found in imperial China. In certain periods, there were “litigation masters” (song shi) who provided help to the people in litigation, but they were neither organized into a legal profession in the Western sense nor recognized by the state. Ordinary social order largely was maintained in a harmonious and unified way through non-legal means. However, in the twentieth century, this social order was almost completely broken down because of the incessant revolutions, culminating in the Cultural Revolution during 1966–76.

Since the late 1970s, the Chinese legal system has experienced a series of fundamental changes. Tens of thousands of laws, regulations, judicial interpretations, ministry regulations, and local regulations have been promulgated, starting with the Criminal Law and Criminal Procedure Law in 1979.
