The baby is a temporary floating population. He works diligently, from a small restaurant owner to a tea shop manager to a bar manager. This film records the survival state of children centered and gay comrades: trivial, messy, boring, and entertaining themselves. The camera calmly captures every bit of their daily life for more than two years, and as time goes by, the changes the baby presents are more ordinary. The film calmly explains the relationship between "comrades" and "society", and the various small details interpenetrated in the film also metaphorically reflect the changes of today's society
