Last year, I visited the Great Wall e to visit every year. We met some foreigners from America while we were walking up the Great Wall. They were very friendly and we offered to introduce the Great Wall to them. I told them that it was 6000 kilometers long, and there was a famous Chinese saying: 'He who does not reach the Great Wall is not a true man.' What we said made them interested in this wonder of the world. I think China is famous for the Great Wall and we are proud of being Chinese.
