In general,there are several reasons for the prevalence of this phenomenon.On the one hand,some people want to express their strong feelings,and some people release their stress.On the other hand,there are still others who just have a poor sense of public morality.All these may lead to their uncivilized behavior in public places,which greatly damages the environment of the tourist sites.
To deal with such wide-spread image damage of the country.We should arouse people’s social conscience to stop staining the tourist sites.The improving of manners and behaviors of the people is a constant work,and it should begin from the very beginning of school.
