Starting from Dingjie County, on the third day, we walked to Salquling Temple. At Sal Quling Monastery we got a ride to the top of Nila Mountain. After climbing Mount Nila, we were able to reach the town of Hiya that night as planned. There was a thick pile of snow on the top of Nila Mountain, and the wind was so strong that the cotton clothes and pants could not stop the cold air seeping in. The four of us were divided into two groups at the top of the mountain, and Geng Xin went to see the lake on the top of the mountain. Because I was walking slowly, I was afraid that I would delay the original trip, so I took the first step with the family dinner. Brother Happy also went down the mountain with us because he had other plans.

Although the snow is thick in Mount Nila, the snow on the road has been shoveled clean. The three of us circled down the hill along the road. Halfway up the mountain, a police car came from behind. The police car came to an abrupt stop next to us. I think that the Tibetan people's police car is different, and when they saw us carrying heavy bags, men, women and children, they took the initiative to help. After the police car stopped, a middle-aged policeman got out of the car, and as soon as he spoke, I realized that things were not what I thought it was at all.

The police told us that we could not go any further, and that they were taking us back to Dingjie County on the orders of the chief. I asked why? The policeman's uncle said that first, our border pass can only go to Dingjie County, and second, we are going to Karmagou, in addition to snow road hazards, there are also snow leopards, bears and wolves, which are very dangerous. Let me say first, we have spent a lot of money on this border pass, and the travel agency and the Armed Police Frontier Corps have clearly stated that the Dingjie County written on the card is not a designated county seat, but refers to all places under the jurisdiction of Dingjie County. Moreover, we have passed through a number of public security and border armed police checkpoints along the way, and we have never heard any objections, otherwise we would not have been able to go all the way smoothly, and we would have returned to Lhasa long ago to find a travel agency and the armed police frontier guard corps to theorize. Second, we come here from thousands of miles away to travel, not to explore. When we arrived in Chentang, we would ask a local guide to take us through the Karma Valley, and we would never act rashly. For us, safety also comes first.

Uncle police said it was also for our good. Last winter, a tourist was in distress in Karmagou, and almost all the local public security and armed police were dispatched to the rescue, and it took a whole week to find the tourist who was no longer human. For the sake of this one tourist, how many manpower and material resources have been consumed by the country. I said that the accounts are not calculated in this way, if they are calculated in this way, why should the country open the door and reform and open up? Just shut yourself up, and keep everyone in the place of birth, as before. Uncle police also tried to convince us. It is said that tourists can come during the tourist season, so why bother to come at this time when the climate is not good and the scenery is not good. I said that after I didn't talk about it, I was old and could still walk now, and I couldn't say what happened next year. In addition, the scenery is different in each season, and what we see at this time is a different scenery.

I understand what the police uncle means, and I understand the police uncle, we spent so much time, energy, and material resources to walk from the county seat for three days to get here, just because of the dangers we may encounter, it may add trouble to the public security and the armed police. The policeman's uncle said that in this case, he would have to report to the chief before he could decide. He picked up the phone and spoke in Tibetan.

After a while, the policeman's uncle said that if we insisted on entering the Karma Valley, we must issue a written guarantee stating that we would be responsible for all the consequences. They tried to persuade us again and again, but we insisted on not listening. In this way, if something unexpected happens, they will also explain it when asked about it above.

Speaking of the letter of guarantee, I suggested to the police uncle that since we were not well educated, I was afraid that it would be difficult for them to satisfy what we had written, so it would be better for them to provide a template, and we would copy it and sign the famous painting and pledge it. so as not to waste their time. The policeman's uncle thought about it and agreed to my proposal. The police uncle is the police uncle, and a guarantee letter is completed by dividing five by two. The glorious task of copying the guarantee letter was completed by Brother Happy, because there was no ink on the car, and the police uncle drove us to the village down the mountain.

Brother Happy was responsible for going to the village committee with the police uncle to copy the guarantee, and Jia Yan and I were guarding the luggage on the side of the road and waiting for Geng Xin, who went to the mountain to see the lake. Geng Xin definitely didn't know what we encountered at this time, and when the guarantee was released, we did it for him. After a while, Brother Happy came out of the village committee, took the guarantee in duplicate, and asked me and the family banquet to sign the guarantee letter separately, press the fingerprint, and write the ID number, and the matter was over. Because Geng Xin was not there, the police uncle did not agree to be signed on behalf of others, and insisted that he should sign and draw the detachment. In the end, the policeman's uncle took away the two guarantees and drove to the mountains to find Geng Xin, saying that one of the guarantees would be signed by Geng Xin and handed over to Geng Xin to bring back.

Four days later, our group of four arrived at the Nadang border checkpoint. For the same reason, we wrote another copy of the same guarantee. This time, Brother Happy, who is familiar with the road, will do it single-handedly, and the rest of the people are only responsible for pressing the handprint.

After receiving the guarantee, the person in charge of the border checkpoint left his contact number, saying that we wrote the letter of guarantee, not that we would ignore the situation. The letter of guarantee just states that they have done the work that needs to be done. The person in charge said that the soldiers under him had no experience in the field, and to a large extent, when they encountered danger, they exchanged their lives for our lives.

I felt that the person in charge of the border checkpoint said something very tragic, and I heard it as if our group was no longer traveling, but trespassing into the tiger's den in Longtan and holding on to the life of nine deaths.
