"Good Night Quote" by He Ruobi of Sui Dynasty. Among the existing qin works, it first appeared in "Song Xian Guan Qin Score". "Songxianguan Piano Score" is the representative work of the Yushan Qin School. Liang Xiao Yin is also one of the representative pieces of the Yushan Qin School.

This qin piece has a delicate structure, a melodious melody, a quiet and fascinating style, and is a fine piece among the ditties. Since its advent in the Sui Dynasty and prevailing in the Ming Dynasty, it has been deeply appreciated and valued by qin masters, and has been included in many qin collections, including: "Song Xian Guan Qin Score", "Da Huan Ge Qin Score", "Tianwen Pavilion" "Qin Score", "Ziyuantang Piano Score", "Wuzhizhai Piano Score", "Qin Xue Chujin", "Shimengzhai Piano Score", "Xingxin Piano Score", "Qinxin Zhizhi" and so on.

The inscription of "Xingxin Qinpu" wrote: "The song is based on the light breeze of the moonlit night, and the elegant evening. The style of the song is delicate and euphemistic, fresh and quiet. It is a fine product for the beauty and fun." Its meaning is that the left hand presses the strings firmly and squarely, the right hand picks the sound clearly, the chanting should be hidden, and the chanting should not be excessive, flowing in richness, and losing its elegance. The rhythm of this piece is moderate, and the fingering is mostly based on common methods, so it is suitable for beginners. This song was also my finger-opening song when I first learned the piano.

Learning guqin, on the basis of being familiar with and comprehending the genealogy and teacher's inheritance, it is also necessary to understand, learn and appreciate different styles and styles of guqin, in order to broaden horizons, broaden thinking, increase experience, learn from the strengths of others, so as to improve own appreciation and aesthetic ability.
