Dear Mai!
Last summer, I was let my parents go to play in Nha Trang, Phong was very happy! The view here is very beautiful. After renting a hotel, my parents went to the beach to swim. The scene here is very crowded and bustling. I want to go with my friends later. I also know how to swim, Phong! After swimming, I went back to the hotel to rest with my parents. In the afternoon, go sightseeing and shopping. Seafood here is very delicious. In the evening, go for a walk in the sea and join the games here. Truly playing here is fun. I'm very sad when I'm home. Come on Phong, I stop the pen here. I wish Phong good health.

Dear .........
How are you doing? I'm writing to you from Kołobrzeg at the Polish Seaside. I'm there with my family. We have a great time, though the weather isn't so good, as we'd like. Therefore we spent our first day on a campside, where we are staying. Yesterday morning we climbed up to the lighthouse and the view were really great. And in the afternoon we went to the beach, where we were sunbathing and we were having a bath in the Sea. Tomorrow we're taking a treepboat on the lake next to our campside and in the evening we are going shoping and then eating ice-cream.
On Saturday we're buying some suvenires and on Sunday we're coming back home.
Anyway, I'll tell you everything, when you will arrive to me next week.
Hope to see you!
Bye for now!
