The floor at home was damp, arched and even broke, and even arched after reloading, and now the doors can&;t be closed.

The simplest, practical and cost-effective way is to spread old newspapers or paper covers on the floor, and replace them again after all the newspapers or paper covers have absorbed moisture. Although it is troublesome, it is the most useful. Personally, I think it is not cost-effective to buy a moisture absorber for a few days a year.
