Last summer I go to Hangzhou with two Americans. I became their guide. First, we went to the West Lake, that is a famous place of interest in Hangzhou. We looked around it by the boat. After that, we went shop. The sellers couldn’t speak English. Though it was very harder, I tried my best to listen their words carefully and translate the sentences. They bought many things with their help. Next, we went to a small zoo but took some pictures. When we felt hungry, we went out and had lunch. After lunch, we visited some old house. All of us had a greatly time that day.
