Is tourism harmful?
crackdown(严厉的打击） eg.Police are launching a new crackdown on drug users. commercial（贸易、商业） eg.In recent years commercial, cultural, travel and other contacts have proliferated between Europe and China. I believe that the cultural tourism can focus on the following aspects: first,tourists should improve cultural quality, do civilized travel,don't do some damage to the culture, and timely reminder of the uncivilized behavior of others. Second, the tourist guide and the scenic spot management office should discourage the uncivilized behavior of tourists. Third, the media should increase the degree of exposure,so that people gradually realized the seriousness of the uncivilized travel. Finally, the government should implement some punitive measures according to the behavior of the passengers, improve the relevant laws and regulations. I believe that these problems will be solved step by step.
