How do you feel about walking on the Sichuan-Tibet line, the Yunnan-Tibet line, the Qinghai-Tibet line and the New Tibet line?

Qinghai-Tibet Line: It is the shortest route into Tibet. The road conditions are good, basically asphalt roads, with many transport vehicles, so there are many traffic accidents. The Qinghai-Tibet line has a high altitude, starting from Golmud 100 kilometers and reaching the Kunlun Mountain Pass at an altitude of more than 4,000 meters, so many people will have a high rebellious attitude. There are many wild animals along the Qinghai-Tibet line, including Tibetan antelopes and donkeys, and they can also pass through Hoh Xil. Starting from Golmud, the Qinghai-Tibet line basically rides at an altitude of more than 4 kilometers and needs to cross the Tanggula Pass at an altitude of more than 5,200 meters, so it is called Tianlu. Although the Qinghai-Tibet line has a short journey and good road conditions, it is not easy to ride the whole Qinghai-Tibet line. Yunnan-Tibet Line: It starts from Lijiang, Yunnan, ends in Mangkang, Tibet, and joins the southern section of Sichuan-Tibet Line. The scenery is similar to the Sichuan-Tibet line, and you can see plateau scenery, hillside canyons, blue sky and white clouds, and snowy meadows. It is the lowest route for the Caspian Sea to enter Tibet. Yunnan-Tibet line is a colorful route to Tibet. National Highway 2 14 can pass through Shangri-La, Zhongdian, and you can see Yulong Snow Mountain and Haba Snow Mountain. If you are lucky, you can see kawakarpo in Feilai Temple. Most of Yunnan-Tibet railways are berthed oil routes, but serious landslides and broken roads often occur. South Line of Sichuan-Tibet Line: At present, the south line of Sichuan-Tibet Line is the route that cyclists choose to enter Tibet the most. Because this route is the most beautiful in Tibet, it is also called the landscape avenue in China. The tour of this route is perfect, the scenery is good, the road conditions are good, and the service facilities along the route are relatively perfect. You can find a place to eat and stay every day according to the planned itinerary. In the peak season of June and July, cyclists pass by this road every day. The Sichuan-Tibet line has beautiful scenery, and the mountains and valleys along it, especially the Linzhi area, are called the Little Jiangnan of Tibet. Riding the Sichuan-Tibet line has to cross 14 peaks, of which two are above 5000 meters and ten are above 4000 meters. It will span the Dadu River, Jinsha River, Lancang River and the upper reaches of Nujiang River. When the weather is fine in Zheduo Mountain or Gaoersi Mountain, you can see Gongga Snow Mountain, pass through xinduqiao, which is known as a photography paradise, as well as Ranwu Lake, Midui Glacier and Lulang, which is known as Little Switzerland in the East. It is very beautiful and full of pastoral flavor. New Tibet Line: As the most dangerous of the four routes to Tibet, even the perilous Shu Road can't compare with it just by listening to the name "Road to Death". On the new Tibet line, there are only endless Gobi desert and snowy mountains and barren hills. After going deep into the hinterland, it often stretches for hundreds of miles, and there are no man's land everywhere, but its magnificent beauty is immeasurable. In the continuous steep Daban, continuous thin oxygen and high altitude may make you suffer from high reaction. If you go alone, I'm afraid you can only taste deep despair alone.
