Should I eat or play vegetables?

The idea of playing music with vegetables came to Nan Weidong, 43, and Nan Weiping, 41, only two years ago, but it has since become a passion and a career.

- If the water content in vegetables evaporates, the tune will become higher than the basic tune or go out of tune. Therefore, the vegetables have to be solid and hard. We can't use vegetables left over from other days - says Nan Weidong.

The Nan brothers have appeared on many talent shows in China and often receive payments of up to 8,000 US dollars for one performance.
