Ceremony held to commemorate emissary Zhang Qian in NW China

Descendants of Zhang Qian offer incense on the ceremony in memory of Zhang Qian, in Chenggu County, northwest China's Shaanxi Province, April 3, 2018. Zhang Qian, a royal emissary in China's Han Dynasty (202 B.C.-220 A.D.), traveled westward on a mission of peace and opened an overland route linking the East and the West, a daring undertaking which came to be known as Zhang Qian's journey to the Western regions.
