7. What are the characteristics of Tibetan Diaolou, Beijing Siheyuan, Northeast Inclined Roof House and Yunnan Bamboo House?

1. Tibetan bunker is a common residential building form of Tibetan people in southwest China's Qinghai-Tibet Plateau and parts of Inner Mongolia. This is a house built of rubble or mud, which is three or four stories high. Because it looks like a bunker, it is called a bunker.

2. Siheyuan is an ancient and traditional cultural symbol of China. "Four" represents east, west, north and south, and "combination" is the shape of a mouth, which is the basic feature of quadrangles. Courtyard houses are elegant in architecture, exquisite in structure and numerous in number, and Beijing is the most popular. Beijing is dotted with quadrangles of all sizes, forming a living environment that conforms to people's psychology, maintains traditional culture and has harmonious neighborhood relations.

3. The sloping roof in Northeast China is mainly due to the heavy snowfall in winter, and the large slope of the roof is conducive to snow removal and reducing the roof load.

4. Dai bamboo house is a kind of dry-column residence, which is mainly distributed in Xishuangbanna, Dehong and Simao in Yunnan Province. These places have a tropical climate with abundant rainfall. In order to cope with the humid and rainy climate, Dai people use local bamboo to build houses.
