Who composed the piano music of Shanquan?

Cui's piano work "Mountain Spring" is a masterpiece of Chinese piano works, which was created in the early 1980s and selected from "Four Folk Songs". The biggest difficulty in playing "Mountain Spring" lies in the control of timbre. We should not only play a wonderful timbre, but also achieve the unity of timbre, contrast and great change, and accurately express the music content and image by using the subtle changes of timbre.
