The theory of words meanings network was proposed by Zhang Qingyun and Zhang Zhiyi and was proved. The first thing about this theory that the foreigners who study Chinese should know is that the words meanings are systematic, including the combination system and development system of synonymy, antonymy and ambiguity. The meanings or words are a network system. About the system, students who study Chinese should know the words meanings can be divided into units and the combination of these units can form certain relationships and community with order according to certain structural relationship.

The words meanings system is one of the language systems. It is the main basis of vocabulary system. Teachers in Chinese language program in China may tell you that words meaning system is a big one needs firm theoretical basis to prove. There are three bases for it, one of which is that the systematic objective things decide the system of the words meanings. Another one learners who study Chinese should know is that the system depends on the systematic thinking ways. Besides, it is universally believed that the language is systematic after Saussure’s theories.
