Nantong in east China's Jiangsu Province is one of the four major kite-production areas in the country. It's particularly famous for the Banyao kite, a large, hexagonal whistling kite adorned with exquisite decorations and vibrant colors. Yao Chunhua, an inheritor of this intangible cultural heritage, has been promoting the art form for 38 years, hoping that more young people will carry on the tradition and spread its popularity around the world.
