Aerial photo taken on Aug. 12, 2018 shows a winding mountain road of the Gyirong Pass highway in Gyirong County of Xigaze City, southwest China's Tibet Autonomous Region. The Gyirong Pass highway, a 94-kilometer section of the National Highway 216, is an important trade route connecting China and Nepal. The road was heavily affected by the devastating earthquake in Nepal in April 2015. Now the road has resumed vitality and taken a new look after years of repairing and renovation, while annual trade volume of Gyirong Port almost grew seven-fold from the post-quake period to top 2.8 billion yuan (414 million U.S. dollars) in 2017.
