Zhang Guodan, an ethnic Dong woman from Liping county in Southwest China's Guizhou province, produces short videos showcasing the culture and life of people in her hometown and sells agricultural products via livestreaming to boost local industry and rural vitalization.

Dong choral singing, a polyphonic vocal tradition performed without musical accompaniment, often makes an appearance in the videos. The 32-year-old has been trying to become a recognized inheritor of this world intangible cultural heritage since 2015 and now promotes it through social media.
