Bronze horns, also known as blowing gold, are ancient ethnic and Han lip-vibrating musical instruments. Bronze horns are one of the "horns" of musical instruments, and there are other musical instruments such as ox horns and bamboo horns. Originally a musical instrument of ethnic minorities in northwest China, it was widely popular in ancient times and was a folk musical instrument commonly used by people of all ethnic groups in northern and northwestern China.

When playing the copper horn, the upper end of the horn is held in the left hand, and the air flow enters from the shallow cup-shaped mouthpiece to make the sound. The sound is majestic and powerful, and there is no fixed pitch.

When playing, those with smaller horns should hold the horns with both hands to play; those with larger horns should hold the bottom of the horns with the left hand and place them in front of the chest, and hold the horns with the right to play. The horn has no sound hole and no fixed pitch. Depending on the mouth shape change and breath control, different pitches can be played. The small ones have a high-pitched and sharp tone; the large ones are thick and melodious, and can be used for solo or ensemble. Use gongs and drums to accompany the ensemble.

In some areas of Hunan, there are also popular horn tunes such as "Jade Emperor Fu", "Lao Junfu" and "Goat Passing Au".
