This romantic drama, named for the famous Kangding folk song, focuses on the lasting love between Li Sujie, a young Han Chinese engineer, and Dawa, a Tibetan serf. The couple meet in 1950 when Li arrives with the Chinese army during the establishment of the Ganzi prefecture. Obstacles force a 60-year separation, but their love never wavers. Adding a parallel modern relationship, the story reflects social changes over time and celebrates local culture.
