While cursive script, caoshu, is known for its spontaneity and expressive freedom, a closer examination reveals an underlying sense of order and balance within its apparently chaotic forms.

We will begin by acknowledging that although caoshu appears unrestrained, it still adheres to certain principles of rhythm, flow, and structure. This emphasis on underlying principles will reveal the subtle structural framework of the script.
