This kind of situation is not common in real life, but it may appear in some novels. If the person wants to go to the no man's land and doesn't want others to know, it might be because he or she wants to experience life alone and get rid of the pressure and responsibility of the outside world. In the novel, this person might choose to escape from reality and live alone in a no man's land. There, he/she would be able to live as he/she wished without the pressure and restrictions of society. However, this lifestyle was not safe because there could be dangers in the no man's land and it was difficult for a person to survive. If you want to go to no man's land, it's best to prepare in advance, such as bringing enough food and water, as well as the necessary equipment and tools. At the same time, they also had to understand the environment and situation in the no man's land in order to prepare for it. In addition, it's best not to go alone. It's best to find like-minded people to go together so that they can support each other.
