Instruments played by the legendary swordsman, Dong Fangbubai and Jet Li.

Erhu, also known as "Huqin", appeared in the Tang Dynasty and is called "Xiqin", which is a folk musical instrument in the north. It is generally believed that today's Huqin is developed from Xiqin, and now it has become a unique stringed instrument in China. It is not only suitable for expressing deep and sad content, but also suitable for describing magnificent artistic conception.
