On National Day, we had a long holiday. It was seven days. I went to Hainan with my parents. My grandparents live in a beautiful village in Hainan. We visited them. We went to see the blue sea every day. We went swimming in it . We went fishing, too. My grandma cooked good food for us every day. The seafood was tasty. I like it. We took many pictures. I was excited.
