1. It is good for drifting alone. The drifting distance is relatively far, and there are many rapids and slides. 2. Before I went, I learned whether it rained in the first two days. After I went to the rain this time, I looked at the water like the Yellow River. The mood was not beautiful in an instant. 3. There are still 60 kilometers to drive off the highway, including 15 kilometers of Panshan Cement Road and a few kilometers of very narrow roads. 4. Unicom cards have no service in the local area, and they can't contact friends. Combined with the above points, the rafting experience is 80 points, the highway ➖ 20 points, the Unicom mobile phone has no signal ➖ 20 points, because the water quality is poor after rain ➖ 25 points, the comprehensive evaluation is 35 points
