The ancient legal form of "law" has stability, normativity, and universality, originating from the Shang Dynasty. During the Warring States period, Shang Yang used it as the name of a legal code. Except for the Song and Yuan dynasties, all legal codes throughout history were called "law", which is the most basic and important legal form in ancient China. In the "Six Classics of Tang Dynasty," it is mentioned that "law" is used to convict and punish, while "order" is used to establish normative systems.
