The river is the only river in Jiayuguan that people can see with the naked eye. It originates from the Qilian Mountains and has been flowing into the Heihe River. It is about 260 kilometers long. The main supply of river water comes from glacier ice and snow and groundwater. "Traising" is the transliteration of the ancient Huns, meaning "a lot of hares." There are two kinds of legends about the name. The first one is that people think that this river is coming quickly, like a rabbit. . The second is that in ancient times, the locals saw hordes of rabbits on the banks of the river. People first saw the rabbits and then saw the river. In fact, no matter from which legend, the importance of this river to the local people can be seen. Each small section of the Shanghe River Grand Canyon has the same effect, but on the spectacular, the section of the Grand Canyon cable bridge, the ice ditch, will be even better. The ice ditch is the closest to the Qilian Mountains and belongs to the Heihe River system. The tributary, so this section almost brings together the snow and ice melt of half of the mountains. From the top down, the river is hidden from the bottom of the valley. The river is thick and narrow from the original spaciousness, and the water flow begins to become turbulent. Urgent, but this section of the river is also very clear and clean, as if you can look at the bottom of the river at a glance, its color is mainly blue-blue, like a god-given pure transparent opal, but also a desolate life The Grand Canyon adds a vibrant color. Such a spectacle is absolutely comparable to the famous "Colorado Grand Canyon."
