   On National Day, we had a long holiday. We had seven days. I went to Hainan Island with my parents to visit my grandparents. They live in a small house, but it's beautiful. We went to see the blue and clear water every day. We swam in it. We went fishing and had seafood. My grandma cooked good food for us every day. The food was very delicious. I like it. We took many photos. I was very happy.
