How to prevent moisture in rainy weather in South China?

1, timely open the window to prevent moisture and ventilation. Even in the rainy season, it is necessary to open the window. In humid weather, the way to open the window should be to close the doors and windows facing south or southeast, that is, to open only the doors and windows facing downwind to reduce water vapor from entering the room. The air from the south wind is the wettest, and the furniture will be moldy if it is not done.

2. When the weather turns fine, all doors and windows can be opened to accelerate the evaporation of water. However, the outdoor air humidity is at the highest value at noon, so it is not suitable to open the window. It should be adjusted in the afternoon or at night when the climate is dry.
