Why is it forbidden to travel to Hoh Xil without filing?

? Because going to Hoh Xil is risky. I think it is a very good rule to file a record before going to Hoh Xil, because Hoh Xil is the largest no-man's land in China. Since it is a no-man's land, there must be hidden dangers when you go to play, then put on record to leave a way out for yourself, not afraid of 10 thousand, just in case. Many people went to Hoh Xil to play in the first two years, but a few people went to Hoh Xil and never came back. Therefore, it is very important to put on record before going to Hoh Xil, which may save people from the quagmire. The first thing to pay attention to when playing outdoors is filing. Filing is really important. No matter where you go to play, it's convenient to put it on record. Let me talk about things that should be paid attention to when going outdoors. The first thing is to remember to file with your parents and friends. To go to a special place like Hoh Xil, you need to go to the relevant departments for filing. This is very important. Once something happens, your parents and friends can quickly locate your position and then come to you. But if you don't put it on record, it will be difficult to find you. Even if the technology is so advanced now, it will take a long time to accurately track your position.

? The second point is to keep in touch with the outside world. The importance of this is self-evident. In any case, we must keep in touch with the outside world. For example, things like charging treasures must be prepared. If you play in a remote place, you may need to prepare a lot of charging treasures. You can't tell what will happen, but if you keep in touch with the outside world at any time, you can let others find you in time and accurately, and when you are in danger, you can let others help you quickly, so you still have to keep in touch with the outside world, and you can't cut off contact with the outside world under any circumstances, because if you break contact and something unexpected happens, then this will be difficult to deal with. So try to keep your mobile phone open at any time, and also consider wireless signals. Mobile phones in the wild have no signal and no power, which is equivalent to garbage, so it is necessary to maintain the communication function of mobile phones.
