There are 53 rivers flowing into the Yellow River in Yulin City, all of which are short-flowing. The four major rivers in Sichuan are Huangfuchuan, Qingshuichuan, Gushan, Shichuan, Kuye River, Buwei River, Jia Luhe River and Wuding River. Based on the erosion of the Yellow River, the flow into the Yellow River flows from northwest to southeast (including three times in the upper reaches of the Wuding River). Branches extend from downstream to upstream.

The lower reaches of this big river are bedrock canyons, with a great decrease in proportion and few tributaries. The valley in the middle reaches is generally wide, the floodplain terraces are developed, the rivers are wide and shallow, and the larger tributaries are concentrated in the middle reaches. The upper reaches are mostly developed in ancient gullies, and go deep into the loess (the bottom part is cut into bedrock) canyon, with steep downhill and more sentries. The direction of water flow is controlled by valleys and gullies in ancient topography, and there are many tributaries, but they are generally straight.
