Advantages and Disadvantages of Tu-zhang-fang on Building Materials Advantages.
Building materials are obtained from local sources, and the building is in concordance with the environment, and having ecosystem rationality.
At last, Tu-zhang-fang needs few building materials, which mainly can be obtained from local sources.
Experimental use of soil materials should come from more than two Tu-zhang-fang in different areas of Yi minority’s settlements.

Meanwhile, green hotel should reduce purchasing disposable goods, try to purchase large packaging goods; and should purchase green raw materials, select safe, pollution-free green food raw materials.
The building and decoration materials of guest rooms should be “green decoration material,” or “ecological decoration material” with no pollution, and low energy consumption; therefore, it should avoid using plastic board or wallpaper that may cause allergic reaction, instead of that, it can choose unprocessed wood, bamboo, and rattan products.
The process includes three aspects: the production of food raw materials must conform to the green standards; the channel of food raw materials must comply with green standards; and the production process must comply with green standards.
