Draw on the wall in The Story of the Stupid Wolf

There is a wall in the square of the forest town. Children like to scribble on the wall. Mayor Owl invited Mr. Niu to repaint the wall to make it neat and beautiful. He ordered no one to scribble on the wall. At this time, when the stupid wolf passed by the square, he saw the white wall. He felt it was a pity not to draw on the wall, so he picked up the chalk and began to draw. Mayor Owl saw it. Mayor Owl severely punished Benlang and made him write a review. When dad took the stupid wolf through the wall, dad took out the chalk and wrote on the wall: Please don't scribble on the wall. At this time, Mayor Owl saw it again. His eyes were wide, like two bullets, and he wanted to shoot out of them. Let the silly mother hand over ten forest coins and pay Mr. Cattle. Mother Stupid Wolf agreed. Before returning to work, they wanted Mr. Niu to type a receipt, but they didn't bring a pen and paper. So the stupid wolf had an idea and wrote the receipt on the wall. Mr Niu agreed very much, so he wrote a receipt on the wall. Mayor Owl was very angry and asked Mr. Niu to repaint it. I think this story is really funny. ...
