Different valence patterns of Chinese parts of speech from 3 different Chinese dependency syntactic networks were extracted in this study and their similarities and differences are presented. The results show that there are some persisting properties of Chinese, which are not affected by style. Other parts of speech are more sensitive to style in Chinese. The advantages and disadvantages of the network approach are discussed at the end of this paper. The network approach to linguistic study can make the complex data concise and easy to understand. However, it also has some deficiencies. First of all, when the network size is large, the structure will become so complex that easy understanding is impossible. Secondly, although the network can easily provide an overview of the language, it usually does not allow analyzing language details.
