Migrant workers who write their daily labor into songs. Once lost voice, from the bar to the construction site work, the music flame in the heart dimmed.

Yan Liuzhu from rural Xinxiang, Henan, conducts daily inspections of the distribution box. At work, he hummed songs from time to time; in his spare time, he will write lyrics for workers under hard hats, and continue his love. Yan's singing always brings everyone a sense of relaxation and joy.
