Ancient Chinese wooden houses, why can experience thousands of years for rotting? And the same can be for human shelter from the wind and rain

Ancient Chinese wooden building houses, construction of timber selection is also an article, are selected high-quality such as teak, cedar, etc., with the current artificial forest timber or short-growth timber is not the same. In ancient times, due to transportation difficulties, wood is used to tie into wooden rows of water transport, transport time up to two or three years is also a normal thing, the wood by the water soak fully moistened, water is completely absorbed in the wood fiber, resulting in a natural chemical reaction to achieve a natural anticorrosive so that the external air is difficult to enter. My personal experience has seen someone will be an old house on the demolition of cedar sandalwood, with an axe for firewood with an axe, axe chopped up sparks straight explosion, visible hardness is how high. Some folk live without water-soaked wood installation before the wood surface repeatedly brushed tung oil, to achieve the purpose of anticorrosion.

Structural brick walls, roof item tile whether it is green gray tile or glazed tile. Ancient people do things rigorously, selected clay raw material mud embryo after repeated crushing fist fight smothered ripe, embryo molding density is good, the appearance of size standards. Burned into a brick and tile weathering strength are not comparable to modern. So after thousands of years of non-corrosive and immortal, of course, can be a shelter for human beings.
