The south is wet and rainy, and some wooden products such as cabinets and beds are covered with mold. How can we prevent mildew?

I am from Guangdong, so I know the trouble of moldy cabinets, especially when the weather in the south comes back, my computer desk and drawers are covered with mold. Then my experience is to go to the supermarket to buy some moisture-proof pills and put them in a moldy place. Just open the window for ventilation at ordinary times. But don't open the weather when you go back to the south. Buy some water absorbent (desiccant) and put it in the cupboard. Or you can clean up the mildew spots in the cabinet with a little 84 disinfectant, and then find a little quicklime and wrap it on each floor of the cabinet ... If it is impossible to say that it is absolutely not moldy, you know the weather in our south.
