Spring is a good season to fly kites. You can fly your kites in the park, in the field or on the play ground. There are many different kinds of kites. Some look like birds; Some look like planes and some look like butterflies. People often fly kites on a sunny and windy day. And the best month for flying kites is March. How can we fly our kites in the sky. First, we run with our kites against the wind. Then when the kite can fly in the sky, you can just stay there with your string reel(线轴) in your hand.
