1, keep the dormitory ventilated, and close the doors and windows at night or when you leave on holiday. Humidity should be taught at night, and ventilation should be at sunny noon.

2, put desiccant in the clothes pile, there are two kinds of hygroscopic boxes and dehumidifying bags. There are also some small sachets and insecticides that can be scattered in the wardrobe or folded quilts.

3. If you leave the air-conditioned dormitory before the holiday, you can try to use the dehumidification function on the air conditioner, which may reduce the chance that the clothes and quilts will be moldy and damp.

4. Don't leave thin cotton clothes, which are more likely to get moldy. This summer vacation, I have a cotton white shirt and a pair of leggings in my closet that are moldy.

Put some lime in the dormitory to absorb water when you leave during the summer vacation, and be sure to wash and dry the quilt before you leave. The clothes put in the closet should also be clean, and if possible, try to take them home.
