My name is Trung, and I live at 52 Tran Hung Dao Street. My hobby is learning about different festivals in Vietnam. Last week, I took part in a flower festival in my hometown. It was much busier than I expected, but the atmosphere was wonderful. I saw many beautiful types of flowers from all over the country. To stay healthy after a long day of walking at the festival, I drank a lot of water and went to bed early. My cousin, Lan, who is very active, also joined me. However, she forgot to wear a hat and felt very tired the next morning. I suggested that she should take some medicine and stay in bed. Next weekend, we are going to visit the National Museum. It is about ten kilometres from my house, so we will get there by bus. I hope we can discover more about our traditional culture there.
