Guzheng, also known as Han Zheng and Qin Zheng, is an ancient national musical instrument of the Han nationality, which is popular all over China. It is often used for solo, ensemble, instrumental ensemble and accompaniment of song and dance, opera and folk art.

Known as the "King of Music" and "Oriental Piano", it has a wide range, beautiful timbre, rich playing skills and strong expressive force, and is one of the important national musical instruments unique to China.

The structure of the guzheng consists of a panel, a wild goose column, strings, a front yueshan, a string nail, a tuning box, a piano foot, a back yueshan, a side plate, a sound outlet, a bottom plate and a string piercing hole. It is a rectangular wooden sound box, and the string frame "Zheng Zhu" (that is, Yan Zhu) can move freely, with one string and one tone arranged in five tones.

As early as the Warring States Period from the 5th century BC to the 3rd century BC, guzheng was widely spread in the area of Qin State (now Shaanxi), so it was named Qin Zheng, with a history of more than 2,500 years. The origin of guzheng is still inconclusive.

Early traditional Zheng music was divided into Zhejiang School, Shandong School, Henan School, Hakka School and Chaozhou School. In modern times, the differences between schools have been very small, and almost every school has its own strengths.

Since the Qin and Han Dynasties, guzheng has gradually spread from the northwest of China to all parts of the country, and has been integrated with local operas, rap and folk music, forming various schools with strong local styles.

Traditional Zheng music is divided into two factions, North and South, and now it is generally divided into nine factions. As Cao Zheng, a theorist and educator, said, "Nine schools are in China", and their Zheng music and playing methods have their own characteristics.
