Children's Day is on June 1st. On that day, all children are very happy. We don't go to school. Most of the children go to the park. In the park, some children are flying kites, some are playing football, and some are playing a game. In the sky, there are a lot of kites. Once a year we will have this happy festival. I think Children's Day is the most important holiday for children. Because every child has fun on that day!
