Recently, in Tianzhu Tibetan autonomous county in Gansu province, located deep within the Qilian Mountains, the fields are lush, and plateau summer vegetables have entered their peak harvest season. Villagers shuttle through the verdant plots, busy picking lettuce stems. The green fields, the winding mountains stretching for thousands of miles, and the speeding high-speed train together form a harmonious picture of clear waters, green mountains and beautiful ecology. Relying on its rich ecological resources and the convenient Lanzhou-Zhangye High Speed Railway, Tianzhu Tibetan autonomous county has vigorously developed specialty agriculture, ecological tourism and other industries, charting a path toward ecological beauty and prosperity for its people.
