Erhu is one of the ancient national stringed instruments in China. The earliest record of erhu was in Song Dynasty, and it was called Huqin or Nanhu Lake. "This is the earliest written record about Hu Qin. According to historical records, the predecessor of Erhu may be "Western Qin". In the northern part of Xi in the Tang Dynasty, people used bamboo pieces rubbed between two strings to pronounce. 1 1 century, there was a record about Xiqin in Le Shu, a music theory work in the Song Dynasty: Xiqin was originally a musical instrument, but it was similar because of its strings. Xibu's favorite music is well done and tied with bamboo, which has been used by the people so far. " In the Ming Dynasty, You Qiuzi's "Autumn Banquet in Tanglin" painted a huqin, which is very similar to the current erhu, that is, the dragon head curled its neck, the second string tied with a ponytail, and there were thousands of pounds tied together.

Liu Tianhua was an outstanding composer, performer and innovator during the May 4th Movement. He designed the erhu with new specifications, fixed the rules for tuning the strings, created twelve erhu solos and forty-seven etudes for the first time, standardized the folk erhu, made it enter the classroom of colleges and universities, and initiated a new stage in the development of erhu performance art. ..
