Liu Sanjie is a story that originates from the Zhuang minority people; the largest of the minority groups in China. It’s based on the legend of a woman called Liu Sanjie (literally meaning “third sister of Liu family”). Across generations, the story has become an oral tradition amongst these people and similar characters have even been found to exist in other minority cultures. According to legend, Liu Sanjie had the gift of a beautiful singing voice from a very early age. So beautiful was her voice, she could quell anger and raise the spirits of the people around her. The story became famous around China when the movie Liu Sanjie was released in 1960 – a rare musical production in Chinese cinema.
