In traditional Chinese instrumental music ensembles, due to the traditional pop polyphonic musical texture, there is no functional harmony, and there is no so-called "bass part". Therefore, various instruments mostly play melody, and there is no special An instrument that plays the role of bass and accompaniment.

The traditional Chinese music aesthetics is the pursuit of high-pitched and bright timbre.

With the infiltration of Western music ideas into Chinese music and the establishment of Chinese orchestras at the end of the 19th century and the beginning of the 20th century, the traditional Chinese music ensemble, which is mainly based on the melody of Jiahua Unison, was gradually influenced by the mainstream harmony in Europe.

The bass part occupies a very important position in Western harmony. Chinese music has been "Europeanized", influenced by the traditional functional harmony and orchestration of the West, but it lacks bass instruments that can support the entire band, forcing contemporary musicians Using Western bass instruments: cello and double bass. But in a "Chinese" orchestra, using this "Western" (especially the appearance) instrument is always unreasonable. So musicians have developed a bass instrument that is completely, or at least looks like it was invented by the Chinese.
