Guqin timbre is clear, pure, implicit, deep and long, which is very suitable for expressing people's thoughts and feelings. Guqin has always been the favorite musical instrument of China literati. Literati not only use guqin to express their deep desire, but also use it as a tool to cultivate self-cultivation and cultivate sentiment. Guqin has a very sacred position in the minds of literati.

The music written by Xue in the Tang Dynasty said: "The musician is happy, can teach with considerable wind, can capture the soul, can argue with feelings, can enjoy feelings, can be brave, can be secular, can be ghosts, and this kind of happiness is also good."

"Custom Yi Tong" said: "Ya Qin's music is also unified, but the gentleman is always in charge, and the piano is the closest and never leaves. Although I was in a poor house and alley, I still didn't lose my piano. Qin Xue has the function of self-cultivation and is not artistic. Loud but not noisy, flowing but not smelling, quiet but not smelling are enough to get along with people, touching people, and achieve the purpose of peace of mind, self-cultivation and self-cultivation

Guqin can not only cultivate one's morality, but also preserve one's health. Self-cultivation is the psychological level, and health preservation is the physiological level. Moral cultivation is not only to appreciate the sound of the piano, but also to understand the content and taste the ideological connotation of the sound of the piano, thus affecting and regulating one's thoughts and behaviors. Health preservation is because playing guqin makes people feel calm, the five internal organs coordinate, the healthy qi rises, and the evil spirits drop, so as to achieve the purpose of health and longevity.

People long for inner peace and a pure land of mind outside the busy work and noisy world, and guqin is the best tool to realize this desire. Ordinary musical instruments make people feel excited, but guqin can make people feel calm. Any kind of art can relieve people's pressure, but the art expressed by guqin is richer, deeper, more delicate and more vital.

People who really love guqin will not think that guqin is just a musical instrument, but a Tao, a spiritual instrument with profound connotation. The ancients had to take a bath and change clothes, burn incense and wash their hands before playing the piano. This is not superstition, but respect for guqin. Guqin is a mentor, a lifelong friend and companion.
