I always dream that I will have a chance to travel to Shenzhen. During the last summer vacation, my mother took me to Shenzhen. I have been there only once, but I still can not forget the beautiful place. Have you ever been to Shenzhen? If you haven’t been there, now I’d like to tell you what Shenzhen is like. Shenzhen is a modern city in South China, it lies next to Hong Kong. I fell in love with it when I arrived there. Shenzhen is very young and beautiful, too. There are many scenic spots there, for example, there are two famous beaches, named Da Meisha and Xiao Meisha. People always go swimming there. There are also a lot of mountain parks there like Lianhua Park and Bao’an Park, they are covered with green tall trees, grass and colorful flowers. Go to Shenzhen when you are free! I think you can have a great time there.
