Now,today is a festival called Chongyang festival which I will talk about. When Chongyang festival comes,people who are far away from home usually go to climb the maintains where they see their families or think about their fimilies. They also want to have a feeling like at home. Besides,people usualy go some shopping and eat some special food.
