How do you feel after passing through Sichuan-Tibet line, Yunnan-Tibet line, Qinghai-Tibet line and New Tibet line?

Fortunately, I have traveled all these routes. The Sichuan-Tibet line (3 18 south line) and the Yunnan-Tibet line are on Mangkanghe Road. Generally speaking, the biggest feeling of walking on these routes is that the different scenery on the plateau makes us open-minded and forget our troubles. In fact, there are only a few kinds of people who come to the plateau to travel: the first kind: it is entirely because they love plateau tourism and like the vast world under the blue sky and white clouds; Those who like photography can be classified into one category; The second type: usually working under great pressure, come to the plateau to decompress; The third type: emotional frustration, come out to find excitement. The difference between these lines is that the Sichuan-Tibet line and the Yunnan-Tibet line start from Chengdu and Kunming respectively, which is more convenient than the other two lines, and Chengdu is the capital of leisure food, and the 3 18 line is also the most abundant landscape of these lines; Dali, Lijiang and Meili Snow Mountain in the first half of the Yunnan-Tibet line are also good; The Nujiang Grand Canyon, Ranwu Lake, Laigu and Midui Glaciers behind Mangkang River Road are also good. Linzhi March Peach Blossom, Nange Bawa Peak. Because of the high altitude along the Qinghai-Tibet line, it is not suitable for entering from Golmud, but suitable for going from Lhasa to Golmud, Tibet. Along the way through Tuotuo, Yanshiping, Naqu and other places. They are all above 4000 altitude, which is very unsuitable for accommodation and easy to cause high reaction; The landscape of the Qinghai-Tibet line is rather monotonous. The new Tibet line starts from Saga County and follows the source of the Yarlung Zangbo River. Holy Mountain and Lake, Guge Dynasty, Zada Tulin, Bangong Lake, Jieshan Daban, Sanliyingpan, Dead Man's Ditch, etc. , all the way to Yecheng and Kashgar; The first half of the Ali South Line is known as the roof of the world; There are both natural scenery and human landscape; But the extremely high altitude also makes few people go; Moreover, it is not recommended to take the new Tibet line in the opposite direction of Xinjiang. I'll add something about this when I think about it.
