Abstract: This paper has discussed how a discourse system is constructed in disciplines, and pointed out the three logic statements:the discourse system in discipline comes as result of historical evolution; the longer its history is, the richer and more mature it is and the system is powerful and full of life only through long historical selection. Based on the discussion, two deductions can be gained that a different independent discourse system can be constructed in different independent disciplines and civilizations and a discourse system itself can be built along its own historical evolution. It finally concludes that China can and should construct its own discourse system along with 5 000 years of civilization.
