Qian Qi, who composed the music for the production in a month and a half, also made several visits to Langzhong.

Xiaoyao Ge, or the Song of Freedom, a catchy melody that incorporates memorable elements and is the production's theme song, was performed by Wu Tong.

Qian blended elements of rock, funk, jazz and traditional Chinese music.

"The full soundtrack is approximately 60 minutes. I blended symphonic music, world music, ethnic instruments and electronic music, allowing them to interweave and complement each other," says Qian, a professor from the Department of AI Music and Music Information Technology at the Central Conservatory of Music.

"Xiaoyao Ge is a dynamic piece that fills the audience with energy and strength. I particularly like the song's vibe, which matches the ancient city of Langzhong," says Wu, who is a renowned sheng (free-reed wind instrument) player. "I hope more people will travel to Langzhong and explore it."
