I think life in the countryside has many advantages. Firstly, people are very friendly. Secondly , the space is very large. We can play, shout or run around without disturbing others. Thirdly, we can go swimming, go fishing interesting things. Moreover, life is peaceful. Then food is very fresh and especially vegetables. Finally , there are a lot of tradition activities that I can join. In short, if I have a chance to live in the country. I think I will be very happy.

         A friendship is very important for everyone, especially me. During my life, I have had many friends. Now I want to tell you about my best friend. His name is Lien Ai .He is a good, kind (and very lovely) person. He supports to me, helps me a lot when I have problems. I love him so much. But we didn't met each other, but I am sure that, if we were in the same school, we will be closer. We've had many memories, we met when we were in hoc24, we have grown to be best friend. When I was sad, he was the first one who encouraged me. When I'm in troubles, he is the most helpful. He isnot only my friend, but also my relative. He supports me in bad times and good times. And he always believes in me, I feel lucky when being his friend. I love him so much.

Where I was born and grew up in Hanoi. The city’s children is a growing modern city. Roads wander wide. The way the two buildings grow up san suicide. Hanoi’s  most beautiful at night, then coats the city as a new coat. Where Where electric lighting as I am sa. They are the parents area for walking in the West Lake. In the air is cool and fresh. Lake blue, a cosmic giant carpet. Coastal lakes are found standing tilt touches down in their reflected nothing more of a young woman doing coast. I am very proud of themselves as citizens Hanoi. The people of Hanoi elegance and hospitality.
