Conch, Tibetan, Mongolian, Naxi, Dai, Manchu, Han and other nationalities play wind instruments. Also known as Li, Fanbei, conch number, law snail and so on. Popular in Tibet, Inner Mongolia, Qinghai, Yunnan, Sichuan, Gansu and other provinces and regions.

When blowing the conch, hold the mouth of the conch with the left hand, press the lips against the mouthpiece to aspirate, and make a whining sound. Each conch shell can emit a basically stable long sound, and the pitch is different due to the size of the snail body, generally between the small character group and the small character group.

The timbre of the conch is directly related to the thickness and size of the thread. Generally speaking, the thinner and smaller the thread, the brighter the timbre, and vice versa. In addition to being used as a ritual instrument in Buddhist monasteries, in nunneries in Tibetan areas, blow shells are used to pay homage to the deceased. It is also widely circulated in the Han nationality area. In the Zhoushan gongs and drums in the folk instrumental music ensemble in eastern Zhejiang, the conch is used as a colorful musical instrument. In coastal areas such as Guangdong, Guangxi, and Fujian, the folk often convene mass gatherings by playing conch shells.
