Chánglín
Chánglín lay in the country of Jīngmén, between the Hàn River and the hills of central Húběi. Under the Sòng, lands from Chánglín and neighbouring districts were combined to form a county at the prefectural seat. In 1376 the Míng reduced Jīngmén to a county and absorbed Chánglín, ending the older county’s separate administration.
