Yanjin County (simplified Chinese:盐津县;traditional Chinese:鹽津縣;pinyin:Yánjīn Xiàn) is located in the northeast ofYunnan Province, China, borderingSichuan Province to the north and east. It is under the administration of theprefecture-level city ofZhaotong.
Situated on the banks of the narrowHeng River[1][a] valley, a tributary of theYangtze, the town of Yanjing, Yanjin's county seat, 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 goviral because of its uniqueness and the surrounding natural environment, attracting much attention to the city.[4]
The city is within the valley, along with a highway and a railway but does not have a high-speed train.
Daily slow train service 5635/5636 between Neijiang 内江 and Zhaotong 昭通 passes through Yanjin 盐津 and Yanjingbei 盐津北 (Yanjin North) stations. Neijiang is pretty close to Chengdu. Yanjinbei Station is closer to the city center.
Since at least theQin Dynasty (221–206 BCE), the area of Yanjin was home to theBo people.[5]
During aDuanwu Festival celebration in the late 1800s or early 1900s at Yanjin, 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 July 2006, a 5.1 magnitude earthquake left 22 dead, 106 injured and more than 6,000 homes demolished.[7]
In 2021, management practices to institute an urban rain flood ecosystem were underway in Yanjin through use of thesponge city approach to prepare for high flooding.[8]
