Xun (pinyin: xūn) is a closed-mouthed wind instrument unique to the Han nationality. It occupies an important position in the history of primitive art in the world.

The origin of xun is related to the labor and production activities of the ancestors of the Han nationality. It may have been made by the ancestors to imitate the calls of birds and beasts to trap prey. Later, with the progress of society, it evolved into a simple musical instrument, and gradually increased the sound hole, and developed into a melody instrument that can play tunes.

Xun is a kind of wind instrument fired with clay in ancient times, round or oval, with six holes (eight holes, nine holes, ten holes, double octave, etc., six hole xuns are not common in the market). Also known as "Tao Xun". Pottery is the most common, but also stone and bone.

There are many types of xun, in addition to the traditional oval xun, there are also many types such as gourd xun, grip xun, mandarin duck xun, Zimu xun, niutou xun, and pen holder xun. Most of the traditional xuns are oval xuns, but now there are many kinds of gourd xuns, grip xuns, mandarin duck xuns, zimu xuns, etc. The styles are beautiful and the craftsmanship is fine.
