Fang Xiang (pinyin: fānɡ xiǎnɡ) is a percussion instrument with a fixed pitch that is very artistic in ancient my country. It came from the Northern Zhou Dynasty (557-581 AD) during the Southern and Northern Dynasties more than 1,400 years ago, and later became a commonly used musical instrument in Yan music in the Sui and Tang Dynasties. It is usually composed of sixteen jin plates arranged according to the height of the paste, and is pronounced by percussion with a small iron or wood.

In Cave 220 of Dunhuang, in the dance music picture in the lower part of "Pharmacist Classics", there are 28 bands, divided into two groups, facing each other. Different from each other, they play various percussion, blowing and plucking instruments from the Central Plains and from the Western Regions and foreign countries. If you look closely, you can see that the instrument on the far left of the group on the right is Fang Yan.

In ancient times, Fangxiang was mostly composed of jade slices and iron plates, which were hung in two layers, and the pitch was determined by thickness and struck with a small hammer.

There is a damping device on the piano frame. The height of the entire piano surface can be adjusted, and the angle of the piano surface can be adjusted within a range of 90 degrees, which can be played horizontally or played vertically like a chime and chime.
