What do you mean, hit the south wall? What does the south wall mean?

1, hitting the south wall is hitting the south wall.

2. The south wall is also called "watchwall". As the name implies, "looking at the wall" means that people can't see things directly in the yard outside the gate. When they pass through the zhaobi, they enter the zhaobi to the right, but when they come out, it is the opposite, that is, to the left, which is similar to the drama.

3. This phenomenon of not hitting the south wall and not looking back is a metaphor for someone who is stubborn and doesn't listen to different opinions. It has the same effect as "all the way to black" and "the heart will not die until it reaches the Yellow River".
