Mr. Zhao Songting had the idea of ??developing the flute into a porous form during his lifetime. Following his mentor’s legacy, Dai Ya worked closely with composers and after nearly twenty years of research and repeated practice, he developed The improved eight-hole flute was boldly used in the performance, expanding the scale and making it more perfect, thus opening up new areas for the flute to better adapt to the various needs of soloists, concertos and composers in the new era. In 2000, he wrote "Practice and Thoughts on the Cooperation between Chinese Bamboo Flute and Western Orchestra", thinking about the development prospects of the eight-hole flute from a theoretical perspective.
