I don't know since when there has been a childish legend about the green wall. It is said that if you make a wish on it, your wish will come true.
Zhou Yunjia stood in front of the green wall for the first time and wrote with chalk thrown by someone on the ground, Li Moxia, come back. Li Moxia, come back
A whole wall was written on it.
But Zhou Yunjia's wish was not fulfilled, and Li Moxia did not come back.
He never appeared in Zhou Yunjia's life again.
The green wall is still a green wall, covered with graffiti, alternating between old and new, year after year, day after day.
