(People's Daily Online) Encompassing a full spectrum of geographic features on earth, the section of the G219 national highway, China's longest national highway along its land borders, in southwest China's Xizang Autonomous Region offers breathtaking views of natural landscapes.

Stretching from frigid highlands to tropical zones, the Xizang section of the G219 national highway connects many natural wonders of the world, such as the Himalayan mountains, the world's most magnificent mountain ranges; Mount Qomolangma (Everest), the world's highest peak; Medog county, one of the most biodiverse places on earth; and the Yarlung Zangbo Grand Canyon, the world's deepest canyon.

A journey along the Xizang section of G219 is a geographical feast for the eyes. Travelers can experience dramatic visual transitions from ice-capped mountains to rivers and lakes, from barren deserts to forests and grasslands, and from lofty mountains and deep valleys to pastoral country scenes. Each sight presents a new landscape spectacle.
