In addition, the flowing water at the source of the Tuojiang River comes from the Infinite River and the Pi River, so there are five sources. Moreover, the Minjiang River water network is intertwined and the basin is disrupted. The water of Minjiang River is still flowing in Tuojiang River.
Therefore, unlike other rivers, Tuojiang River is a mixed-race river. But in the end, because Mianyuan River is the longest, it is regarded as the positive source.
