The Longjin bridge at Zhijiang is a Ming-era covered bridge of the Dong country, carrying walkers across the Wushui in any weather. The county around it held the airfield where Japan's 1945 surrender in China was arranged.
Qianyang administered this stretch of the Yuan valley for centuries, and its walls, gates and stele corridor record that rank. The paperwork left for the rail town of Huaihua in the 1970s, but the county seat came back next door.
Hongjiang grew where the mountain routes of the southwest met the navigable Yuan river, and its intact Ming-Qing commercial quarter earned the nickname Little Nanjing. Its newest history is a merger its residents fought and lost.
