18 Days Trip to Tibet

In fact, until now, I have no idea how to describe that trip to Tibet. The Qinghai-Tibet line went in and the Sichuan-Tibet line came out, which lasted 18 days. Of course, I was not the protagonist of this self-driving trip, but I also found the protagonist. The protagonist is not a human being, or not an ordinary person. How should I say? How can I say it, can you understand it? Perhaps this story cannot be explained clearly no matter how I tell it. After all, I am both sober and confused at the same time. I have lived like this for the first half of my life, and I may continue to live like this in the future. Then I'm going to start this one~~
