The soul of the flute refers to a form of musical expression of the soul system of the flute master in the ancient Chu state. Xiaohun is a unique music form, which is mainly characterized by superb piano skills and tragic phonology. Xiaohun's music is slow, deep and melancholy, and can express strong emotions and inner pain.

The history of Xiao Hun can be traced back to the ancient Chu State. It is said that the Xiao Hun System was founded by Zhuang Ziyu, a famous Xiao player from Chu State.
