1, the youngest member of China bamboo flute family, can be traced back to Wuyang bone flute in Jia Hu, Henan Province and Hemudu bone flute in Zhejiang Province 7000~8000 years ago. Most of these bone flutes and bone whistles are made of animal bones. Compared with ancient bone flutes and bone flutes, most of the flutes we are familiar with are made of mahogany, plastic, bamboo and other materials, and their timbre, volume and appearance are quite different from them.

2. 197 1 At the beginning of the year, Mr. Yu Xunfa, a famous bamboo flute player, invented the mouthpiece. He made a double-hole flute with a short bamboo tube cut by the piper, and played an octave (d 1~d2). Two years later, he officially performed on the stage. His first performance was based on the Romanian folk song Lark. Later, in order to increase the range of the two-hole flute, Yu Xun added three finger holes, thus successfully developing a five-hole flute. 1974, Bai Chengren's solo "Morning in Miao Ling", which was specially composed for the five-hole flute, swept the country and made many audiences know the flute.

3. Because the braces are simple to make, low in cost and easy to carry, their unique charm is welcomed by many people, and many people have improved them. Some of them enlarged the opening to facilitate tuning or increase the range, some improved the finger hole to reduce the fingering of half hole, and some made the mouthpiece with different materials. These improvements have continuously enriched the expressive power of the mouthpiece. Now there are all kinds of flutes, including double flutes, five flutes, seven flutes, scale flutes and ding flutes.
