Is there anything particular about connecting the wall?

Even the walls are "adding walls to walls". There is a saying in the countryside that "the wall is added to the wall, and the family is ruined." The meaning is as follows:

1, "Add a wall to the wall", from the perspective of geomantic omen, the courtyard wall of the neighbor's house is higher than that of his own house, which will block his geomantic omen. For rural people with feudal ideas, there is nothing more annoying than this.

There is no way to change the area of the house, because the four beams and eight columns have been fixed when the house is built, so the difficulty coefficient of heightening the house is too great. Even a brick house with a second floor on the roof is risky. Once an earthquake happens, the house will collapse and the family will be ruined.
