Situated on the banks of the narrow Heng River[1][lower-alpha 1] valley, a tributary of the Yangtze, Yanjing city has been referred to as the "World's Narrowest City."[2][3] The buildings of the city are situated on tall pillars, which is a preemptive measure toward water-level rise during periods of heavy flooding.[4] Videos of the city routinely go viral because of its uniqueness and the surrounding natural beauty, attracting much attention to the city.[4]

History

Since at least the Qin Dynasty (221–206 B.C.), the area of Yanjin city was home to the Bo people.[5]

During a Duanwu Festival celebration in the late 1800s or early 1900s at Yanjin city, a bridge that spanned the Heng River collapsed and four hundred people were drowned.[6] This led to the bridge being rebuilt with walls and a roof.[6] The county was named after the city of Yanjin when it was formed in 1917.[4]

In 2021, management practices to institute an urban rain flood ecosystem were underway in Yanjin through use of the sponge city approach to prepare for high flooding.[7]
