在“万山之祖”的喀喇昆仑山, 从“世界屋脊”帕米尔高原的红其拉甫口岸往西,是古丝绸之路西道。沿途是壁立千仞的冰峰雪岭,悬崖峭壁的高山峡谷,平均海拔6500米。空气稀薄,气候恶劣。1966年以前,一条崎岖山路成了中国和巴基斯坦两国间政府和人民往来的惟一通道,但经常因洪水、泥石流等灾害而阻断。 In the Karakorum Mountains, the “ancestor of the Wanshan Mountains,” the west route of the Khunjerab port in the Pamirs at the “roof of the world” is the ancient Silk Road’s western route. Along the way is the erected thousands of peaks Bingxue Ling, cliffs, alpine valleys, the average elevation of 6500 meters. Thin air, bad weather. Before 1966, a rugged mountain road became the only way for the government and people of China and Pakistan to cross the two countries, but they were often blocked by floods, landslides and other disasters.
