This is the first grassland after entering Gannan from Lanzhou. The Tibetan Guozhuang competition is being held. Tibetan young men and women from all over Gannan wear bright Tibetan costumes, sing and dance, in the blue sky, green grassland under the support, like flowers on green leaves, beautiful and beautiful. Fresh air, sputum-loving wildflowers, herbivorous yaks, weave the beauty of the Sanke grassland.
