四川的西北部有片挺拔的高原,地理上称为青藏高原的边缘带。八月是这里最美的时候:雪峰峻峙,芳草连天;经幡映日,牧歌唱晚……当内地大部分地区还在暑气下蒸腾时,这块土地正在欢度一年中最灿烂的时节。虽然春意盎然,高原毕竟是高原,几位行者满怀憧憬向高原进发,谁也未料到,除了美景,面对他们还有种种意想不到的困境。 There are tall and straight plateaus in the northwest of Sichuan and geographically as the marginal zone of the Qinghai-Tibet Plateau. August is the most beautiful time here: Xuefeng Junzhi, grasses and the sky; through the Ying Ying days, pastoral singing night ... ... when most of the mainland is still under the summer heat, the land is enjoying the most brilliant year season. Although spring is full of vigor and vitality, the plateau is, after all, a plateau. Few travelers, with their longing for progress toward the plateau, did not expect any unforeseen difficulties in the face of the beautiful scenery.
