Mapping out history of Hexi Corridor for future

In a significant stride toward heritage preservation, Zhangye in Northwest China's Gansu province has embarked on the "Two Lines Mapping" project to safeguard its cultural relics.

Zhangye, historically known as Ganzhou and located in the central part of the Hexi Corridor where the Qinghai-Tibet Plateau and Mongolian Plateau meet, was a significant commercial hub and strategic passage on the ancient Silk Road, earning the nicknames "Golden Zhangye "and "Jiangnan north beyond the Great Wall". Jiangnan is south of the Yangtze River's lower reaches and famous for its rich local products.

Boasting a long history and rich heritage, the city was designated by the State Council as a national historical and cultural city.
