Guzheng has beautiful timbre, wide range, rich playing skills and strong expressive force, so it is deeply loved by the broad masses of the people. Now there are also small guzheng, portable guzheng, mini-guzheng, semi-guzheng, new guzheng and twelve-average-tone-modulated guzheng. Guzheng is an ancient national musical instrument that accompanied the long-standing culture of China and was born and raised in this fertile yellow land.
In the early days, traditional Zheng music was divided into two schools, namely "South Zheng" (Chaozhou Zheng) and "North Zheng" (Henan Zheng and Shandong Zheng). The entry "China Music" in Singerov Music Dictionary published in Britain wrote: "China Zheng is represented by Henan and Shandong schools in the north and Chaozhou Zheng school in the south."
With the development of the times, in the 20th century, on the basis of the North and South Zheng, several other schools were derived, namely, "Chaozhou, Shandong, Henan and Zhejiang", and the difference between them and the contemporary schools has been very small, and almost every school has its own strengths. Now it is generally divided into nine schools, as Cao Zheng said, "Nine schools flow to China", and the Zheng music and playing methods of each school have their own characteristics.
