The bronze bell (pinyin: Tóng líng) is a musical instrument of the Miao and Zhuang nationalities. It is popular in Xilin and Longlin in western Guixi of Guangxi Zhuang Autonomous Region and Yongning and Wuming in southern Guizhou. It is one of the eight tones of ancient musical instruments. The bell is also shaped like a bell, but much smaller than a bell. Made of copper, the appearance is spherical, and the specifications are different. The larger one is about 5 cm in diameter, and the smaller one is about 2 cm in diameter. The upper part of the bell is provided with a ring-shaped ear for hanging with a rope. The bottom of the bell has a long strip opening, and the length of the mouth is smaller than the diameter of the bell, and the width of the mouth follows the bell. The larger the bell, the wider the bell, the smaller the smaller the bell. The bell contains two iron balls slightly wider than the mouth of the bell. Usually three to five copper bells of the same size are attached to a circular frame or rope.
