The demise of Jiangzhou-
Jiangzhou has maintained the status of twin cities on both sides of Jialing River for at least three centuries. The specific time of the disappearance of its northern Fucheng is impossible to verify, but it will never be earlier than 520 AD (when Li Daoyuan wrote "Notes on Water Classics").
