Wang Boming prepares for a geography class at Yingcai Junior High School in Yinchuan, capital of northwest China's Ningxia Hui Autonomous Region, Oct. 31, 2014. Wang Boming used to be an arts teacher, but he now teaches geography at Yingcai Junior High School in Yinchuan. During his class, Wang can draw an intact world map on the blackboard within four minutes, which he regards as a more direct and engaging way to expose students to geographical knowledge. Wang would also brief his students on the latest world news, the global environmental situation and other facts about countries and regions when chalking world maps. (Xinhua/Chen Junqing)
