The Kam Grand Choirs background music of Ao Run in 'Ne Zha 2'

In "Ne Zha 2," when Ao Run, the beautiful dragon queen of the West Sea, first appears, the background music is truly unique — it's the Grand Song of the Dong.

The Grand Song of the Dong is a polyphonic folk singing tradition of the Dong ethnic group. Performers from several villages gather together to sing, unaccompanied. The songs, which describe the history, beliefs, customs and emotions of the Dong people, are an important part of their cultural identity and contribute significantly to their social cohesion.

Generally sung in the Dong language, which has no written form, they are passed down orally from one generation to the next. Divided into various genres, including narrative and love songs, drinking and funeral songs, they are often accompanied by clapping, stomping and dancing. Sung on occasions such as festivals, weddings and funerals, the Grand Song reflects their wisdom and creativity, as well as their harmony with nature.
