Problem with water coming out from the walls

My cousin in Macau is complaining how hot and humid her house is. As she is approaching summer there, it will get even hotter with increasing in humidity. She asked me for information on dehumidifier buying guide. I asked her why she needs one, and she asked me to imagine water come out from the wall. I was shocked to hear she said that. I didn't realize the humidity is so high over there. I came from Malaysia but yet I haven't seen water coming out from the wall. So I know it is pretty bad.

She wants to find out which type of dehumidifier is best for her home. I told her to visit DehumidifierTips.com. She can also find out the recommended features to look for when she is buying one. I am very sure if she will be able to find all answers she has about dehumidifier from there.
