Bells of this type were made in graduated sizes to form a set of chime. Each bell when struck on two different locations at the mouth, emitted two different tones. Zhong bells were hung by a small loop on the shank in order for the bell to swing and fibrate freely. The eighteen bosses on each sides (mei) gave the notes distinctive qualities.
Compare this bell to a similar example of a bigger size illustrated in the exhibition catalogue of Jessica Rawson and Emma Bunker, Ancient Chinese and Ordos Bronzes, Hong Kong Museum of Art, 12 October to 2 December 1990, The Oriental Ceramic Society of Hong Kong, 1990, fig. 50
