Dear ___,
I’m writing this letter to tell you that I've just returned from a trip to Ha Long Bay with my family. The sight was extremely magnificent. It took us five or six hours by car to get there from Ha Noi. We spent more than a week there. The weather was perfect. It was sunny, cool and windy. We enjoyed walking along the seaside at night very much. It was really interesting when we knew about the legenda of Ha Long Bay. We really want to come back there when we have time next year. How are you getting with your study at home? Where are you going for your holiday? Let me know.
Love you,
Your best friend, _____
