From Golmud all the way down to the West Beach, the roadside landscape is a monotonous desert. The mountain is rarely seen green, but the sky is getting bluer and the scenery is getting simpler. When the car passed the ditch, the accelerator was collected, resulting in insufficient momentum of the car and failed to pass the ditch smoothly. We didn't have a towing rope, we could only help find stones, digs or carts. I went ahead to see if I was on the main road. Fortunately, it was smooth and I could keep on going.
