Starting from Shuanghu, follow the road to Punogangri Glacier and walk for a day into the confines of Hoh Xil Nature Reserve. Along the way, Dachao walked in the front, I walked in the middle, and potatoes walked last. We agreed to keep a distance within line of sight. The first two days went quite smoothly, although I was walking in a no-man's land, and I didn't meet a single person along the way, but I could occasionally see one or two off-road vehicles for a self-driving tour to see the glacier.

By the third day, problems began to appear.

The first is that the potatoes ran out of water. From Twin Lakes, we anticipated five days of water, and based on the distance, we were expected to be able to reach the glacier resupply station in five days. But the potatoes drank water very violently, and he was prepared to drink water for five days, and he dried it up in two days. The next night, I mixed a bottle of mineral water for the potatoes. When he got up in the morning on the third day, he drank all the water from the potatoes again.

Although there are many puddles along the way, they are all stagnant water with melting snow, and there are so many bacteria that no one dares to risk it.

Da Chao likes to call potatoes fat. Potato once protested very seriously, either calling him a potato or calling him fat, why add a dead word in front of the fat man? Dachao was asked. Dachao said that there was actually no reason, but it was a little more comfortable to call a fat man a dead man than a fat man.

Although Dachao said that the potatoes drank water too quickly, by noon, the water he brought himself was almost finished. I also have only a small half pot of water left in my large 1500ml kettle. The three of us bumped heads and decided to let the super-manager, who was walking in the front, be responsible for stopping possible self-driving tours or chartered tours, and buy a few bottles of water from the people in the car. We stayed until about four o'clock in the afternoon, and finally the shadow of an off-road vehicle appeared in our sight. Dachao stopped the car smoothly.

I was about 100 meters behind Dachao, and after I saw the car stop, a person got out of the car and didn't know what to say to Dachao. When I approached the SUV parked in the middle of the road, several people suddenly got out of the car, holding various cameras in their hands, and took wild pictures at me. I suddenly saw those bright shots, and I was stunned. Someone asked me questions like where and how old they were, and I just smiled stupidly and didn't answer.

When those people left, they left behind a few bottles of water and a few drinks, and they didn't take any money from us.

After those people walked away, I realized that it was probably because of the dust of my body, the vicissitudes of my face, plus my age, and carrying a huge backpack, which aroused their interest. And I found out that I was hiding the problem of motion sickness.
