SAPA ATTRACTIONS: THE ROTPROOF WOOD HMONG HOUSES
The rotproof wood Hmong houses
To build the walls and roof of their houses, the Hmong and the Dao use one of the most popular woods in the area, peumou (Fokienia Hodginsii) also called "coffin wood" because the Hmong and the Chinese like to bury their dead in it. 

Insects do not attack peumou and it does not deteriorate when in contact with water. Roofs made of peumou shingle will last up to 70 years. Some can be seen in Cat Cat, Lau Chai and Tavan.
