I from Washingston D.C. I'm writing to you from my city. I love my city very much. It's got lots of famous places and special food. It is a beautiful city. Some tourist came here and all of them commanted it was very interestin. It's got some beautiful parks like: Lac Hong garden, Tet Mau Than park,etc. It not only has some beautiful parks, it also has a lot of historic districts. Historic districts are places you cand find information about history of something. It also has plenty of malls like Nguyen Kim supermarket, Dien May Xanh , Coopmart,...Specially,the malls in my city are not only for young people, but also a destination for many foreign tourists. When you feel sad,tired,unpleasant you can go to the coffe shop after working hard in company. In this place, you can chat with your friends,relax or play games. The food and drink are very rich here.The most important is the people in my city are very friendly and kind. They always help poor people,..If you want to see a picture I will send you a part of my city.
