The movie music Yu is also the theme song of the movie Yu. The music "Yu" was created to match the tone of the film "Yu". Ren Guang went deep into fishermen's life and deeply experienced the state of fishermen at that time. The songs are euphemistic and lyrical, which can better reflect the hardships and aspirations of the working people in China in the 1930s.

The film "The Story of Yu" begins with the music "Yu" on the East China Sea. Through the experience of a fisherman's son and a boatman's master, this paper reveals the wandering and turbulent life of the lower classes in old China at that time. Director Cai Chusheng, who experienced the seaside life in his childhood, knows well the hardships of fishermen's life, and uses this film to show this miserable life at the bottom.

Ren Guang's other works:

He wrote the famous Yu (1934, the theme song of the movie Yu), as well as March of the Earth (1934, the episode of the empty valley and the orchid) and Moonlight (1936, the lost lamb).

The Cloud Chasing the Moon is an early masterpiece of Ren Guang, a young composer in China in 1930s. At first, it was a national orchestra. Later, the author used western composition techniques from an innovative perspective, adopted the European "tango" dance rhythm, and absorbed the beautiful and relaxed timbre and musical composition characteristics of China Jiangnan silk and bamboo. So as to create this small instrumental ensemble with far-reaching artistic conception, comfortable and beautiful appearance and full charm.
