Regarding 318, Lhasa is actually not important to you, and 318 is not important to you. You just need to spend time thinking while walking, and you need beautiful scenery. Therefore, the goal of your departure, based on the current reasons, should be : I want to write some words that record the beauty of nature, and I also want to try to think.
So when you are on the road, if you see a beautiful place, try to stay for 3-4 days, if you can, it is no problem to stay for a week, and then during that time, observe everything there, and then write it down, When I finally arrived in Lhasa, during the one-month rest period, I sorted out those words, and then wrote some relatively complete articles. But in this case, there should be no one whose itinerary is the same as yours, but remember not to go on the road alone. (Remember the site URL: www.hlnovel.com
