Tongbai Mountain Range is located in the western part of the hilly region of southern Henan, a border area between Henan and Hubei provinces.
This place is the source of the Huai River and also the watershed between the Huai River and Yangtze River. The northern side belongs to the Huai River system, while the southern side belongs to the Yangtze River system.
