Huobusi (pinyin: huǒ bù sī) is a Mongolian plucked musical instrument. It was found in the Yuan Dynasty and was popular in the Ming Dynasty. It was included in the national music in the Qing Dynasty. It is spread in Xinjiang, Inner Mongolia, northern Gansu and Lijiang Naxi Autonomous County in Yunnan Province.

Folks call it Hu Bu'er or Hu Bu'er. Popular in Inner Mongolia Autonomous Region, Hebei Province and northern Gansu Province and other places. Four-stringed, long-handled, fretless, and pear-shaped speakers were quite popular among the people in the Ming Dynasty.

In the Qing Dynasty, Mongolian music was listed as one of the national music. Except when it was played during the feast of Mongolian princes, it was also played on the first day of the first lunar month, the 15th dynasty meeting of the first lunar month, and when Mulan was walking around.

Huobusi is also used in folk instrumental ensembles, and it is still used today in the Shifan Club performance in Donghan Village, Yi County, Hebei Province. The traditional Huobusi is shaped like a rice spoon, with a long piano rod and a small resonance box. Because the sound box is covered with a film, the sound is full of strong grassland flavor.
