Recently, a famous basketball player has caused public angry by writing on the Great Wall. In the fact, this happens in many place of interest. I had some suggestions to solve this problem.

First, make more posters to inform the public the damage of graffiti (涂鸦). Besides, punishments, such as a fine, is necessary to tourists with so bad behaviors. Also, I think it’s helpfully to put up some boards along the tourist attractions that tourists can leave messages.

I’m sure with our efforts, more and more people will become concerning about protecting cultural relics.
