This has something to do with people's ideas. Most of the houses that rural people live in are single-family houses. Right in front of the yard is the gate, which faces the living room. In the process of building the gate and living room, the hall must be higher than the gate.
In the concept of the older generation of rural people, the hall represents parents and elders, and the door represents future generations. If the gate is higher than the hall, it means that children and grandchildren are above their parents and elders, which is very unfavorable to rural families.

This proverb is also reasonable from a scientific point of view. From the perspective of modern architecture, the height of the hall is generally higher than the gate. This is because if designed in this way, the air in the hall will form a virtuous circle with the outside world, and the people living in it will not feel bored.
The design of the hall higher than the gate is the scientific achievement of our ancestors, which is especially important in the south with high humidity. Because if the gate is higher than the hall, stagnant moisture will form in the hall, which is very harmful to human body. Although "family failure" is exaggerated, it will also affect health. If you live in it for a long time, you will even feel chest tightness and shortness of breath, and you are more likely to get sick.
