Write a green word on the wall. Why?

The green word "demolition" is the same as the red and white word "demolition". According to the plan, they were all demolished.

The words in the demolition area are generally unrelated to the color, but the purpose of removing a circle of calligraphy and painting is to prevent some people with ulterior motives from using slogans indiscriminately. It is equivalent to the act of stamping, emphasizing standardization and legitimacy.
