Geographical factors:
China is located in the northern hemisphere of the earth, in the east of Eurasia. Most of the land is located in the north of the Tropic of Cancer (north latitude). The sun rises from east to south and sets in the west. In winter, the height angle of the sun is small, and the doors and windows of the house face south, which can let more oblique sunlight into the room, thus increasing the indoor temperature.
In summer, the height angle of the sun increases, and the light in doors and windows is relatively less, thus keeping the room cool. Then, most of our country is located in the East Asian monsoon region, and the houses all face south. In midsummer, you can avoid the direct sunlight in the hottest afternoon, and in winter, you can avoid the cold wind in the northwest, which plays a role in preventing cold and keeping warm.
