This vacation I went to Hainan with my parents.We went there by plane and it was my first time to take the airplane,so i felt very excited.The weather in Hainan was fine.I did lots of interesting things there.First,I went swimming in the sea.The sea was blue and clear.We were easy to see the sand in shallow sea.Then,I picked up shells on the beach.The shells were quite beautiful and I liked them a lot.I picked up for a long time,but I still only picked up a few.At last,we went shopping in a big shopping mall.We bought some seafood because it tasted really delicious.In a word,I enjoyed myself in Hainan on vacation.I hope I can go there again.
