On March 28, more than 90 kites flew in the sky at Kunming No 1 High School, Yunnan. Over 1,200 students and teachers happily ran and flew their kites. And they made these kites themselves! All their kites were traditional hard wing kites from Yunnan. This kind of kite has a history of more than 600 years. Unlike other kites, it is stereoscopic (立体的). So it can fly high even if the wind is strong.
