It rained for several days, and the weather was against the tide. There are many drops of water on the partition wall ceiling of the room. Why?

There are two reasons:

1。 The ceiling is wet, too, but the moisture in the ceiling can't go up. Because it is the roof, it can only gather into water droplets from the cracks in the ceiling.

2. There is water leakage on it. Open a small piece of the ceiling and look at it with a flashlight. If there is a leak on it, it is easy to see a large area of moisture.
