Dear xxx:
How do you do?
I went on a trip to Hainan today with my family .We went there by plane. After we got off the plane, we went to the beach to see the beautiful sand and swim there. There were other people there too. Some people were surfing and some people were diving in the deeper part of the sea. Afterwards we had lunch at a seafood restaurant near the beach. We ate seafood like shrimps and craps, and drank some abalone soup.
We all didn't want to go home because the scenery was so beautiful, and there were so many other exciting things to try,but sadly it was time for us to go.
It was definitely an exciting trip.If I have a chance to go there again, i will be more than happy to visit the place again.
Yours
Sincerely
xxxxx
Dear 你朋友的名字
This is 你的名字. I am in Hainan, China now! It is really a great place and I am here for vocation with my family. The weather here is so nice and people are very kind, too. We enjoyed swimming everyday. I also love the food here, it is very different from my hometown. I hope you will enjoy your summer, too. If someday you will come to China, I will definitely bring to to Hainan and we can have fun together.
Take care
Sincerely
