Cao Jun, 41, is a flute maker in Yuping Dong Autonomous County, Tongren City, Guizhou Province. In 2010, he learned the damage repair skills of the flute, and he is highly praised by the flute lovers.

In 2006, the Yuping flute making skills were listed as the first batch of national intangible cultural heritage list by the State Council.

In order to solve this problem, Cao Jun carefully explored and researched the repair work of the xiao flute according to the damaged parts and forms of the xiao flute reported by consumers. , The repaired flute can not only ensure its sound quality and sound effect, but also match the original appearance in appearance.

"The repairing technology of the flute is very particular, especially the polishing technique. If the force is not properly adjusted, the flute will be damaged twice, and even the flute will be scrapped directly!" Cao Jun said.
