let me tell you something about my trip to the Great Wall. I went to the Great Wall with my friends Li Leilast Sunday. It took us about an hour to get there by bus. It was hot and sunny that day. There were thousands of people on the wall. We walked on the wall about two hours. We met a group of foreigner and talked with them in English. I bought a book about the Great wall and my friend bought a pair of sunglasses .We ate our lunch at a restaurant.We didn't go home until 3:00 in the afternoon.
