Zheng, also known as Zheng He, is an ancient traditional plucked instrument in China (2265438 BC+0-207 BC). The plucking of the zither spread among the general public, blending local folk music and forming local schools with different musical styles and playing techniques. It is deeply rooted in China folk music culture, and has been circulated for more than two thousand years, so it is commonly known as "Guzheng".
Guzheng has a wide range, clear timbre and rich expressive force, and has been deeply loved by the public. Before the Han and Jin Dynasties, the Zheng had twelve strings, and later it was increased to thirteen strings, fifteen strings, sixteen strings and twenty-one strings. Guzheng's famous songs are: fishing boats sing late, mountains and rivers flow, playing in the water in the western Western jackdaw, autumn moon in the Han Palace, rain in the banana window and so on.
