My hometown is very beautiful. It’s a quiet village. It is not far from the city center. It takes only 40 minutes by bus.There is a lake in front of my hometown. We often row boats on the lake. You can see lots of two-floor buildings. There are many red flowers and green trees around my hometown, so the air is very fresh. People in my hometown are very friendly. They know each other well. Some families raise cows and others grow wheat. We enjoy our life here. I think it is a wonderful place to live. I hope you can come and visit soon.
