How to order bottled water in Tianjin Urban Construction University

College students order bottled water from life teachers. College students order bottled water to use in the dormitory, and the water delivery workers in the water supply station cannot enter the dormitory. Bottled water is sent to the middle point of the first episode downstairs in the dormitory, which is kept and sold by the life teacher. When the dormitory needs bottled water, they will go to the life teacher to order it. This is how college students order bottled water.
