In the past few years,more and more Chinese people have been to foreign countries for sightseeing,which is a good phenomena.But a few tourists didn't pay attention to their images.There were some tourists washing his feet in a washing basin in Thailand.And"someone was here"was written in Chinese on the places of interest in foreign countries.
Having read the news,I felt shocked and ashamed for their uncivilized behaviour.They not only destroyed a historical relic,but also damaged Chinese tourists' reputation.I think travelling is a learning experience for tourists and they should learn how to absorb local culture and raise awareness of the importance of cultural relics and proper behavior.
In a word,no matter where you are,try to be a civilized tourist.
