Liu Yang He, a landmark in Hunan province, is not only the film’s original title but also a well-known Communist folk song in China. It was written during the Agrarian Reform that precedes the Cultural Revolution. Youngsters were sent to farmlands and factories to experience intense labour. They sang to praise Chairman Mao. Kah-kah (Rain Lau) was permanently injured in an industrial accident during that time. When Kah-kah meets this amputated client (Ko Hon-man), they feel sympathy with each other and turn this sympathy into a possibility of love as if they were flowing into a river of no return. Here, Rain Lau’s sophisticated performance resembles her award-winning role in Queen of Temple Street (1990).
