Traditional musical instrument making skills (Hongyinzhai Shengguan making skills)
The Hongyinzhai Sheng and pipe making technique is the traditional handicraft technique of producing Chinese folk wind instruments in "Hongyinzhai" founded by the Wu family in Beijing. It is the only musical instrument making technique in China that has been passed down from the Qing Dynasty court. In the late Qing Dynasty, Beileye Wu Qirui made musical instruments and passed on the court skills, which have been passed down for five generations in the Wu family. The Wu family followed the traditional skills and maintained the court style. They domesticated the wood and bamboo, hollowed out, drilled, and tuned them for artists, and innovated the folk wind instruments to make Chinese folk wind instruments into a series, which contributed to the cause of Chinese folk music and has high folk music value, art collection value and historical research value. In the 1980s, Chinese art masters named the Hongyinzhai Sheng and pipe instruments "Wu's Wind Instruments". This skill has high technical content and talents are hard to find, so it needs to be further protected.
