Dear editor,
I am Wang Ping.a seniorthree student.I found a very serious problem that there're many tourists painting anywhere they were visited.When I was went to the scenic spots ,I found there's too many graffitis(涂鸦) anywhere,painted on the wall,carved in stones(刻在石壁上),just like someone came here for a visite.
I think it's a very bad phenomen
