Children fly kites on the bank of the Lhasa River in Lhasa, capital of southwest China's Tibet autonomous region, Sept. 19, 2014. Kite lovers in Lhasa have a tradition to "fight kites" on the bank of the Lhasa River from August to October every year. Trying to pilot kites in aerial combat, participants have to make an effort to outmaneuver or disable an opponent's kite in some way. The "kite fighting" in Lhasa was listed as China's national intangible culture heritage in 2006.
