Dongda Machinery Pressureless Feng Men's Bad Joke
Wu Zhen Feng Men was going to attend A Mei's wedding. Because he was about to be late, the car drove very fast and did not stop at the red light. So he was stopped by the Justice Messenger, who was about to issue a ticket for the no-pressure damper. The Justice Messenger asked the no-pressure damper: How do you write "jumping" for running a red light? Wu Zhenmen thought he was going to be late, so he stopped people from coming down, and said impatiently: I can't write! After a while, the Justice Messenger gave the ticket to Wu Zhenmen, and Wu Zhenmen stuffed it into his wallet without even looking at it. A few days later, I went to pay the fine and showed the ticket to the lady at the counter. The lady looked at it for a long time and then said to me: You can go back! No-pressure damper Mo Ge said strangely: Aren't you going to be fined? The lady said: No need! Keep going on red light. There is no such traffic rule!
