Great Wall protection pride of Ningxia county

Wang Shengyan, director of Yanchi county's cultural relics management institute, once considered the local portion of the Great Wall as merely a long stretch of man-made earthen barrier. But since taking on the role in 2007, his perspective has profoundly changed.

Today, the 58-year-old leads a pioneering effort that combines traditional guardianship with cutting-edge digital technology to maintain and protect one of China's most iconic heritage sites in the Ningxia Hui autonomous region.
