Why do you say "don't hit the south wall and don't look back" instead of the north wall, the east wall and the west wall?
The south wall is actually an invisible wall. The south wall is also called the shadow wall. The buildings in our country are basically ancestors who face south, leaving us too much spiritual wealth and hardworking and kind workers, so we have to go left or right when we go out. Through our own wisdom and experience, we have left too many proverbs and proverbs for ourselves. If you go straight, you will definitely hit the south wall! Therefore, there is a saying that "you can't look back when you hit the south wall." There is a wall inside the gate, which is called zhaobi, zhaobi or yingbi. This wall is the "south wall",
In the past, the south wall meant the shadow wall. As the name implies, "looking at the wall" means that people can't directly see the things in the yard outside the gate. In daily parlance, "don't hit the south wall and don't look back" means refusing to listen to different opinions. It means that a person will do something that everyone opposes, and finally he will hit a wall. Synonyms include "don't cry until you see the coffin" and "don't stop until you reach the Yellow River", so it means that he won't die until he reaches the south wall.
The south wall was originally designed to block things that people can't see. Most of the ancient houses in China face south. When the gate comes in, there is a wall called zhaobi, zhaobi or yingbi. In fact, this south wall is not an existing wall, but a shadow wall, which can not only block the sight of outsiders, but also from the perspective of geomantic omen, people used to think that ghosts were constantly patronizing their houses. This wall is the "South Wall". When you come out of the main entrance, you must avoid this wall and walk around, or you will bump into it. The screen wall also has its function, that is, blocking the sight of outsiders, even if the door is open,
Because the south wall is a shadow wall, the shadow wall is a wall facing south in the home, not a visible wall, but is specially used to describe the meaning of other obstacles.
