In ancient China, ethnic minorities in Yunnan, Guangxi, Sichuan, Guizhou, Guangdong, Hunan and other places made bronze drums, which were basically round piers. The drum body was composed of drum body (drum chest), drum waist and drum feet, and symmetrical ears were cast at the junction of drum body and drum waist. Common decorative patterns include sun pattern, frog pattern, heron bird pattern, horse racing pattern, feather dance pattern, Yun Leiwen and horse pattern. The earliest bronze drums were used as musical instruments, usually as a symbol of wealth.
