嘉陵江
The longest stem of the Jialing River, however, can be traced to a source in Aba Tibetan and Qiang Autonomous Prefecture, Sichuan and the entire river is long. This source is located at the head of the Baozuo River, considered a tributary of the Bailong River, itself the primary tributary and main stem of the Jialing River system. The branches named Jialing and Bailong meet in Guangyuan in Sichuan and continue as the Jialing to the Yangtze. The river reaches the floor of the Sichuan Basin at Langzhong and continues in a sinuous route into Chongqing and its junction with the Yangtze River.
