Why can't you hang underwear in the middle of the dormitory?

You can't hang underwear in the dormitory because it is elegant and hygienic.

Because underwear is close-fitting clothes. First of all, putting it in the middle of the dormitory will give people an extremely unsightly feeling. If a guest visits and sees it, it will give people the impression of impoliteness and lack of quality. Secondly, underwear, as close-fitting clothing, has a lot of human secretions and bacterial pollution, even after cleaning, there is no guarantee that there will be residues on it. After being placed outdoors for cooling and ventilation, it can be killed by ultraviolet radiation or taken away by circulating air as much as possible, and at the same time, it can speed up drying.

Therefore, underwear should not be placed in the middle of the dormitory, but should be placed outdoors to cool down.
