South China is suitable for wooden houses?

It can be done, the ancient Chinese wooden house construction is better in the south, and will choose in the riverside riverside. As long as the wood used for special waterproof and insect-proof treatment, is perfectly fine. Of course, you also need to think about protection against typhoons, which come every year.

The treatment of the wood, you have to ask the experts in this field only, or those old carpenters. It seems that tung oil treatment can be done, but I do not know exactly how to do it.
