Roof of traditional houses in northern China

① Slope: The northeast region has a high latitude, a large inclination of the sun and a large amount of precipitation, so the slope of the roof is used to shelter the eaves and drain the rainwater falling from the roof smoothly.

② Wall thickness: The temperature in Northeast China is extremely low in winter, and it is freezing outside, so thick walls should be used to resist the cold wind outside.

(3) small window:

1) The days are long in winter. There is a lot of sunshine (not heat).

2) The inclination angle of sunlight is large. It is not advisable to open windows in large areas to attract sunlight.

3) The temperature is low in winter, which is easily affected by cold wave. So the window area is low, and the ventilation area is less. Match the thickness of the wall to resist the cold.

The most typical residential style in Northeast China is the adobe house facing north to south, with three independent houses being the most common, and two or five rooms are variants of three rooms.

The fundamental reason why the house faces south is the need for lighting and heating. This architectural style caused by the natural environment was finally interpreted as an ideological custom and even developed into a feudal rule with hierarchical nature. In people's minds, north is the top, south is the bottom, and even sitting in the north facing south has become synonymous with reigning over the world.
