Guqin, as the treasure of Chinese traditional music culture, carries the profound historical and philosophical connotation of Chinese civilization. In the world of qin music, there exist three levels of deep understanding of the people - "technology, art, Tao".

First of all, the first level of Guqin is "technology", that is, the skill of the piano. This realm focuses on the mastery of guqin playing techniques, including skilled left and right hand techniques, accurate grasp of the melody, and delicate control of the intensity, speed and timbre of the melody. Piano players need to go through long-term fingering training, master various basic and advanced fingering methods such as "picking, hook, picking, picking, hitting, belt, moving, turning, rolling, brushing", as well as how to correctly use guqin singing 猱 and other techniques, so as to achieve rich changes in music and emotional expression.

Secondly, the second level of Guqin is "art", that is, qin art. At this level, the piano people are no longer satisfied with the simple technical performance, but began to pursue the artistic charm and emotional depth in the music. The realm of piano art requires players to deeply understand and comprehend the cultural connotation behind the music, and transform the music into a vibrant art work through their own emotional injection and unique artistic treatment, so as to convey profound artistic conception and touching to the listeners.

Finally, the third level of Guqin realm is "Dao", that is, Qin Dao. This is a supreme realm that transcends skill and art itself and pursues integration with all things in heaven and earth. Qin Dao is not only limited to the level of music, but also involves many dimensions such as philosophy, morality and spiritual practice. Qin players need to deeply interpret the qin music and improve their inner cultivation, so as to realize the unity of man and qin, and the unity of heaven and man, so that every time they play the qin becomes a kind of exploration and understanding of the universal law and life philosophy.

To sum up, the three-level realm of guqin - "technology, art and Tao", represents the process of skill upgrading from primary to advanced, and also symbolizes the profound progress from skill to art and then to philosophy, which is the goal and ideal realm that every guqin lover and even artist constantly pursues.
