Abstract: Research of Chinese legal culture grew vigorously and declined suddenly, the main reason is that the research conclusion cannot reasonably explain contemporary legal culture phenomenon, and no innovation of methodology is the main sticking point. Culture is a set of rules system, and discourses are a kind of power control rules. Judging by the appearance instead of in-depth study, the scholars may be confused in the narrative discourse of Chinese legal history created by rulers of ancient China. Discourse system of Confucianism ideology with a core of moral determinism dominated the people’s "truth" knowledge and value judgment on Chinese tradition law. Critical discourse analysis from linguistics methods can help people read, interpret or recreate text and discourse cultural connotation through the cover of ideology
