The traditional etiquette(Li) and law(Fa) played a significant role in the past Chinese society. It helped curb people’s behaviors in the old times. Law reflects behavioral patterns and the consciousness of law in a society, while it takes a legal culture to understand the law and the grounds on which laws are based. The legal culture takes place only when citizens are aware of under what circumstances the law may take effect to restrain people’s behavior. The study aims to reflect on the legal culture in etiquette(Li) in the following aspects: the significance of law in traditional Chinese etiquette(Li) and law(Fa), the incubation of the legal culture in terms of etiquette(Li) and law(Fa) and the merging of them, the significance of traditional law from the Western point of view, and it also explores whether the traditional Chinese etiquette(Li) and law(Fa) is a kind of natural law or not. In conclusion, the study finds that the development of the traditional Chinese law differs from that of the West. The traditional Chinese legal culture in etiquette(Li) is a self-sufficient system and can hardly be observed with the Western legal system. But today, when we apply the Western legal values to interpret our law, it does not necessarily mean that we are completely breaking off from the traditional legal culture in etiquette(Li). In doing so, we are trying to remind ourselves how we can do during the process of cultural shocks, absorption and merging, to understand the differences in law and how conflicts deriving from legal differences may be avoided or even fused.
