What kind of experience is there no hot water in the dormitory all the year round?

Our home is close to the northeast, but it does not belong to the three northeastern provinces, but belongs to the central part of Hebei Province. Then the temperature is not particularly cold in winter. There is no hot water in the school all year round. There is only cold water in the school water room, and cold water is used to wash your hair in winter. Now if you let yourself wash your hair in cold water, you will feel that your scalp is very irritating, and then you will have a headache. Maybe you are still young in high school and can withstand the stimulation of this cold water, whether it is washing your face, brushing your teeth or washing your hair.
