Hehe, there may be many reasons for this. Some girls are really shy and don't like others to see their privacy. But it may also be because conditions don't allow it, for example, there is no place to bask in our inner O (∩ _ ∩) O. People, as the saying goes, when the Woods are big, we don't have to take it for granted.

But whatever the reason, it is not good for their health. Especially for girls, after washing, they can hang in the shade for a while to prevent the inside from hardening, and then they must be taken to a sunny place to dry, sterilize and disinfect. But be sure to get it back before sunset.
