The Chao Gong is the most famous in our range of traditional Chinese percussion instruments. Most Westerners love the Chao gong and the wind chime. The Chao gong is made of electrolytic copper and tin. It is almost flat, except at the outer edge, which is set inwards, so that a kind of cylinder is created. For example, with a gong of 25 cm in diameter, the edge is approximately 1½ cm straight up. The entire surface of the gong is slightly hollow (round), in the direction of the side to which the edge also stands. The center and the edge of a Chao gong still have the black layer of copper oxide on both sides that is formed during the process of making the gong. The rest of the gong is polished white. Chao gongs are available in a series from 18 cm to over 2 meters in diameter. The oldest Chao gong was discovered in a tomb in the Guixian site in the autonomous region of Guangxi Zhuang in China. It is dated in early western Han Dynasty (202 B.C. to 5 AD). They were known for their very intense and spiritual sound, which was used in rituals and tribal meetings. According to tradition, Chao gongs were used to clear the way through the city, for dignitaries and during processions, something like the siren nowadays. Sometimes a certain number of strokes on the gong was used to indicate the height of a certain authority. This way two officials, who unexpectedly met on the street, could know who had to bow for whom.
