This paper did up in details directed against the fuzzy, polysemy and ambiguity of Chinese language. This analysis and re-organization can make their definitions, categories, and differences be further understood, which can also function as the reference to the future deeper research. The specific research procedures were as follows: Firstly, a detailed analysis was done to the ‘Fuzzy’ of Chinese language. The ‘Fuzzy’ here refers to the ‘Fuzzy’ in ‘Fuzzy Linguistics’. It has specialized meaning in ‘Fuzzy Linguistics, but different with the vagueness in ‘Vision Vagueness’, ‘Attitude Vagueness’ used in daily life. Its critical feature is the definiteness to ‘Core Semantics’, but indefinite to extensional semantics. Secondly, the ‘polysemy’ of Chinese was analyzed in details. The polysemous words in this paper were only limited to multi-lexical meanings, but not multi-morphemes. The content related with ‘basic meaning’ ‘extended meaning’ and metaphoric meaning’ were summarized according to Polysemy Dictionary of Modern Chinese Language. Thirdly, the ‘ambiguity’ was analyzed particularly. There are four kinds of ambiguity: ambiguity of lexical meaning, ambiguity of phrase structure, ambiguity of active voice and passive voice, and ambiguity of segmentation. Finally, the comparative analysis was done to these three aspects on sememe, extension, and context. This paper further confirmed the connotation of fuzzy, polysemy, and ambiguity which take reference on the further research. In an age of global intelligence, linguistics is no longer an independent discipline, but closely integrated with humanities and natural science, and it's the inevitable trend of social development. Computational linguistics is a typical interdisciplinary research field, the biggest problem which faces is how to solve the ambiguity, polysemy and fuzzy itself. So the research result of this paper lays a certain foundation for the study of computational linguistics.
