During the summer vacation, many people like to go to the beach.  Some swim in the sea, some stand in the hot sun and play ball each other. Some children kneel on the beach, pile the sand castle. There are also some little puppies running on the beach. Children whistle to the dogs and the dogs run to them happily. Children throw the ball to the dogs ,then the dogs run to catch the ball. In addition, there are hot air balloon activities. Some people get into the basket under the hot air balloon. When the staff cut the rope to the hot air balloon, we feel the hot air balloon going up slowly. It flies like a bird.
