What does the rural saying "If the door faces west, Leng Xia will bully you" mean? Is it reasonable?

Rural proverb: "The gate faces west, but Leng Xia bullies". From the overall layout of China architecture, we can feel that it is not the best architectural layout. If the building layout is east-west, especially for the northern region, the door faces west, which is not conducive to heating in winter and shading in summer, it will become a building layout of warm Leng Xia in winter and have a negative impact on the living conditions of the main family. Let's talk about cold ling first: We know that there are more northwest winds in winter, and a cold current from Siberia will blow into the yard and the house at the gate, which will definitely have a negative impact on the warmth of the house. Moreover, the days are short and the nights are long in winter, and the sun usually sets around 5 o'clock. Then, the gate faces west, where the sun rises from the east. Because the main building is relatively high, it will block the lighting in the yard. After entering the afternoon, it gets dark earlier. So, here's the problem. In winter, the whole yard is not well insulated and the lighting is not good, so the indoor temperature will drop. Is the main house not affected by the cold? Be bullied!

Let's talk about bullying in summer: the temperature in summer is high, and the house needs shading to cool down, so the living environment temperature will be more comfortable. Summer is influenced by the earth's rotation, just like where China is, the days are long and the nights are short. It gets dark around 7: 30 in our local area, which means that the afternoon sun shines for a long time, and the afternoon sun is even more sinister. Due to the layout of the door facing west, the courtyard has good lighting in summer, which will cause the indoor temperature to rise. Moreover, there are many southeast winds and few northwest winds in summer, which is not conducive to heat dissipation in the hospital. This will cause the courtyard layout with the gate facing west to be unfavorable for heat dissipation in summer, and it is reasonable for the main family to be bullied by high temperature.

This ancient custom is to remind people to choose the appropriate architectural layout according to the regional climate of China, and let the courtyard choose the best architectural layout according to the four monsoon directions and the change of lighting. Generally speaking, it is not advisable to sit west facing east, but in the traditional sense, sitting north facing south is the most reasonable architectural layout. Whether it is sheltering from the wind and lighting, it is the most scientific and reasonable architectural layout. This also makes the rural houses in China, under favorable conditions, most of the architectural layout is usually the layout of sitting north facing south. This old saying shows the wisdom of our ancestors, who know how to use the "gift" of nature according to local conditions to make the living environment and layout of families more reasonable. For modern people, a reasonable architectural layout can save a lot of heating and electricity bills. Therefore, this old saying has reference significance for both buyers and buyers.
