The Golden Week is coming; it is a good chance for people to travel and relax from their work. Most people choose to visit the hot tourist sites. But some tourists act very impolitely; they get used to making some marks on the tourist sites to prove that they have visited there. It is rude to do that. This kind of thing happens in China more often than in any other country. How do we deal with the uncivilized behaviors during the travel season? In my opinion, we still have to encourage the education of our tourists. Everybody has a duty to protect these places of interest.

Question: What rude behaviors do some tourists do?

参考答案：

They make marks on tourist sites.
