The image is a photograph of a Nao bell, a traditional Chinese percussion instrument. The bell is made of metal and has a round base with a handle on one side. The handle is decorated with intricate patterns and designs. On the right side of the image, there is a text written in Chinese that translates to "Nao bell" in English. Below the text, there are two smaller images of the bell, one of which is a close-up of the handle and the other of which shows the mouth. The text also mentions that the bell was a percussion instrument, which was used to strike during rituals and banquets and signal a retreat during wartime. Such bells could only be used to beat time, not to play a melody.
