Today is a nice day. There are so many people flying kites on the Yangtze riverbank (Or: Many people fly kites on the Yangtze riverbank). Parents go on a picnic with their children beside the Yangtze river. I spend a day watching those beautiful kites in the sky. People make various kites fly in the sky using a kite string. Kite-flying is a traditional activity in China. The history of kites can be traced back to over 2000 years ago, when a men called Modi invented the first kite, which was made of bamboo.
