Chinese rubbing stringed musical instruments. Also known as Quhu and Erxian. Mainly spread in Henan and Shandong, it is the main accompaniment instrument of Henan Quju Opera, Shandong Qinshu and Lu Opera. The predecessor of Zuihu was Xiaosanxian.

According to legend, during the Kangxi period of the Qing Dynasty (AD 1644-AD 1911), the emperor ordered the removal of the court troupe, and the artists had to live in the folk performing arts. One day, an artist's little sanxian was bitten by a mouse. But the performance was about to be performed soon. In a hurry, the artist replaced the thin tungsten wood with the bow of the huqin between the two strings. The musical instrument was born, and this is the falling beard.

According to the textual research, in the period of the Republic of China, Zhu Wanming, an important founder of ququ opera, discussed with some "fanciers" in Datun and Wangtun in the southern suburbs of Luoyang to transform the main instrument of ququ opera.

They refer to the main instruments of Yuetiao and Henan pendants, and based on the three-string, they changed the plate resonance of the three-string into a concertina tube, and covered the top with python skin or snake skin to increase the volume, and the three strings for plucking Instead of two strings, a new instrument was created that had never been there before - he and the artists named it "Zuihu".

Due to its long stem, large barrel, high volume, and soft tone, Zui Hu is very pleasant and suitable for performances in squares and stages. Since then, Zui Hu has been designated as the main instrument of the opera. At the same time, Zhu Wanming and everyone added percussion instruments such as seven cymbals and eight cymbals to the accompaniment of the opera, which improved the accompaniment effect, and suddenly added a grand momentum to the "minor tune" opera and expanded the expressive power of the opera.
