This item was purchased at an antique market a long time ago. It is a Chinese folk instrument, the Zhongruan, in its current condition. It does produce sound. I am selling it because I no longer use it. There is peeling of the coating (lacquer?) around the edge of the body. The hard case is damaged. A 30-year-old receipt from when I bought it at the antique market was also included. Please take a look. As it is an antique, would it be of interest to a collector? Thank you.
