Jinghu, a traditional stringed instrument in China, has a history of more than 200 years and plays a very important role in the accompaniment of traditional opera Beijing Opera. A thin and tough snake skin covers the front of Jinghu organ. After the vibration of the strings reaches the snakeskin, it can only make a sound if it affects the vibration of the air column.

A good Jinghu has the characteristics of "crisp, crisp, bright, thick and slippery". The choice of snakeskin largely determines whether the timbre of Jinghu is complete, and the time of catching snakes and the size of snakes will also affect the choice of snakeskin. However, the life of snakeskin is generally only two years, and it is greatly affected by environment and humidity. Especially in summer with high humidity and high temperature, southern cities are prone to collapse, while northern cities are prone to explosion, which often requires re-skinning, thus consuming a lot of snakeskin.

More importantly, most of the snakeskin on Jinghu Lake are wild black-sheathed snakes, and one snakeskin can only make 6-8 pieces. According to the conservative statistics of China Musical Instrument Information Center, hundreds of thousands of pythons are killed and used to make musical instruments such as Jinghu, and these snakes can eat 6.5438+million mice a year. "Killing wild pythons to make musical instruments is not only costly, but also seriously damages the ecological balance."
