China News Service, Lhasa, May 22 (Danzhen Cidan Pubuzhandui) The Ngari region in Tibet is known as the "Roof of the Roof of the World." 每年五月，冰雪消融，草木发芽，迎来候鸟孵蛋、养雏的最美时节。 In Qulong Village, Daba Township, Zada ​​County, Ngari Prefecture, the quiet Ganima Bird Island has become the "cradle of life". Black-necked cranes, red shelducks, bar-headed geese and other migratory birds nest and breed here, playing a plateau ecological concerto.
