Liu Kai, a junior student majoring in radio and television directing at Haikou University of Economics, wanted to record the old life and "culture of the family" at sea. He invited several students such as Ren Zikuan, Qi Le, Cao Shouxiang, Wen Yi, Yu Li, Bao Yirui, Ji Yutong, etc., and decided to make a documentary.
Liu Kai spent 19 minutes fully showing the production and life of this group of "sea nomads" with the unique perspective of "fishermen's expression"
