Huánzhōu
Huanzhou stood on the grasslands west of the Yuan summer capital, Shangdu. The prefecture originated under the Jin and was restored under the Yuan in 1265. When Kublai ordered a new city built on the Jinlianchuan plain, his adviser Liu Bingzhong selected a site east of the old Huanzhou town; the new city became Shangdu. Huanzhou also lay along the network of postal stations connecting the Yuan capitals.
