Zhong is a generic name for Chinese clapperless bells which appear elliptical in cross-section and feature a concave mouth of opening at the lower end. This beautiful and unique form helps to generate two distinct pitches when the bell is struck. Naiton, or nipples, dragons and bats appearing on the bell's surface are symbolic of fertility and good fortune. Peaches, symbol of long life, decorate the suspension loop (nui) and a bat, representing good luck, links the bell with the frame. Bells similar to this were used in sets for rituals, or may have been played individually on special occasions.
