The upside-down river is because "all the rivers in the world are eastward, only this stream flows westward" and because of the terrain, the river flows upside-down, which is amazing. So I heard that this is the origin of the name of the inverted river. Later, I found many versions on the internet. The inverted river is located in the first town of Qinghai-Tibet Plateau - "the town of inverted river. The town of inverted river is the way to Qinghai Lake. After all, I heard that Princess Wencheng went to Tibet and passed through it. So there is a very large statue of Princess Wencheng in the town. This inverted river is also a scene beside the road. Point, you can visit along the way, the upside-down river is also an entrance to Qinghai Lake. Although the lake is not big, it looks like a very ordinary small lake, but the water here is clear, winding and beautiful. The ticket is 15 yuan to 20 yuan per person, you can wear Tibetan clothes for free photography, you can feel the Tibetan wind around. It usually takes 30 minutes to finish the tour.
