Since the Qin and Han Dynasties, guzheng has gradually spread from northwest my country to all parts of the country, and has been integrated with local opera, rap and folk music to form various genres with strong local styles.

Traditional zheng music is divided into two schools, the north and the south. Now it is generally divided into nine schools. As Cao Zheng said, "nine schools spread across China", and each school has its own characteristics in its music and playing methods.

Chaozhou Zheng of "Hanjiang Sizhu": spread in Chaozhou area of ??Guangdong Province, with special music structure and unique spin method.

The most important thing that makes the zheng unique and different from other instruments is the change of the left hand's portamento, which is the so-called complementing the sound with rhyme. Without this, it is difficult to say the genre and origin of zheng music. develop. In Chao Zheng, the application of this technique can be said to be very wonderful. In fact, when playing the zither, you can achieve several combinations of scales and modes by changing the notes of your left hand, and the temperament is also different from the equal temperament and folk music from other places.

The Chaozhou Zheng is unique with its smooth and gorgeous right hand and the unique way of adding glissandi with the left hand. The changes are delicate, subtle and unique. The main tunes of Chaozhou Zheng include "Chong Liu", "Light Liu", "Liu Wu", "Reverse Line", etc. Among them, the music in "Chongliu" tune is more euphemistic; the music in "Lightly Liu" tune is fresh and lively; the music in "Huowu" tune is lingering and sad, with distinctive rhythms. Among the people, the use of plucked string instruments such as the zither to play ancient music "poetry" is called string poetry music. "Liu Qingniang" is the most popular piece of music in this poem. Although it is not a large suite, it includes four tunes: "Light Liu", "Chong Liu", "Huo Wu" and "Light Three Heavy Liu". It is also beautiful and has the characteristics of Teochew music. In Teochew music, it is called the "Mother of String Poems", which means the mother of music.

When learning Chao Zheng, "Liu Qingniang" is an indispensable repertoire; in addition, "Cold Duck Playing in the Water", "Moon High", "Icing on the Cake", etc. are also commonly used in Chao Zheng repertoire.
