A soldier walks on a road in Zham Town, Xigaze Prefecture, southwest China's Tibet Autonomous Region, April 24, 2017. Zham, once the largest border trade port of Tibet region, is now an empty town. Bordering Nepal, the town was devastated during the 8.1-magnitude earthquake on April 25, 2015. More than 4,250 people were evacuated from Zham four days after the massive earthquake as its geological structure was remarkably changed with possible secondary disasters. Before the earthquake, Zham port cleared about 90 percent of land-borne trade between China and Nepal. (Xinhua/Liu Dongjun)
