An unforgetful trip   　　I went Chong Qing in July is a city which was built near mountains. So people call it Mountain City. In Chong Qing,I went to the Red Stone Center, to see the places which the prisoners lived in the past. It is a terrible and awful trip. There are a lot of dogs, and soldiers with guns near the prisons. And most of the prisons are good, they didn't want to tell the bad people where the other people were. They lived in very small houses. No good food to eat, no good water to had only twenty minutes to stay out side per day but they still said nothing.   　　I think they are the heros in that century. I will follow their spirit.
