Sitting in a house facing east and west, what cities are there in the west?

Sitting in an east-west house, five provinces and cities in the southwest (Sichuan, Yunnan, Guizhou, Tibet and Chongqing), five provinces and cities in the northwest (Shaanxi, Gansu, Qinghai, Xinjiang and Ningxia), and Inner Mongolia and Guangxi in the west. The total area is about 6.86 million square kilometers, accounting for about 72% of the country's total area.

The total population of western China is about 380 million, accounting for 29% of the total population of China. Although the area is quite vast, the population density is relatively sparse. This is due to the poor topography and climatic conditions in the western region, in which the plain area accounts for 42% and the basin area is insufficient 10%. About 48% of the land resources are deserts, Gobi, Rocky Mountains and alpine regions with an altitude of more than 3,000 meters. The annual average temperature is low, and most provinces, autonomous regions and municipalities are below 10 degrees Celsius. The annual precipitation in nearly half of the region is below 200mm, which makes the average population density in the western region below 50 people/km2, far below the national average, which is consistent with the Heihe-Tengchong population demarcation theory put forward by Hu Huanyong.

Sitting east facing west is a concept of ancient geomantic omen in China. It is the crystallization of the wisdom of ancient working people, not a superstitious legend. To people: just look west. For architecture: it is to open a door or window facing west. In short, it is "going back to the East". Simply put: sitting east facing west is the main lighting surface of the house.
