Why did all the ancient houses in China "sit north facing south" and rarely "sit west facing east"?

We often watch TV dramas and find that ancient houses all face south. Although there are many modern residential buildings, this pattern has changed, but most of them have quadrangles in some places, so why not face east from west?

First of all, in order to collect more light, in ancient times, people said that the south was sunny and the north was cloudy, but China, located in the northern hemisphere, naturally had better light towards the man. Moreover, the houses in ancient times were mainly quadrangles, and people lived low from the ground. Sometimes, water vapor came back from the ground. If people didn't bask in the sun to the south, they would easily get sick. Moreover, ancient houses were generally combined with halls, and the actual houses were behind, and there were eaves, so

The second point is that people pay more attention to superstition. The ancients said that the north and the south have different meanings. Generally, the north means failure, so some people call defeat a defeat. So if the house faces south, it definitely means that people's future is a failure, so this moral is not good. But the south is different. The south generally represents hope, so people are willing to change the orientation of the house to the most promising side, which is what people later said.

The third point is that ordinary people actually learn from the layout of the palace. The ancient capitals were basically in the north, so when building the capitals, they usually face the south, which means that they have to accept the worship of the people in the south. Ordinary people also build houses in this way, which is actually a kind of auspicious and noble yearning for the future and life.
