comparative study of Mohist logic and Xunzi logic enables us to understand the content and character of Chinese classical logic, and to sum up its developmental regularity and experience.

After that all of the stabilizers and it s logical operator are also given.

In this paper,we define the mapping from a logical operator set to its corresponding fuzzy rough approximation operator set,and discuss its properties.
