Which is bigger, the deputy director of Quxian detention center or the deputy director of police station?

Same size. Judging from the level of the leaders of the two departments, the director of the detention center and the director of the police station are both metre-level and equally big. It's just that the director of the police station is broader and has greater rights. The director of the detention center has a single relative right. Detention centers are places where criminals and major criminal suspects are held. It is a reform-through-labor institution in China and a temporary institution under the public security organs.
