Which is better, Yunnan-Tibet line, Sichuan-Tibet line or Qinghai-Tibet line?

If you take photos, you can choose Yunnan-Tibet or Sichuan-Tibet routes to enter Tibet. Among them, Sichuan-Tibet also has a southern line and a northern line, and the northern line may have more subjects to photograph. Qinghai-Tibet is high in altitude and monotonous in color, which is not suitable for you, but you can try it on your return trip. The scenery along this road is on the road, and there are not many scenic spots that need to buy tickets. Occasionally, some can be bypassed. In a month and a half, you can easily visit a big ring road and go to Mount Everest. There is nothing to say about the budget. More is less. Many people spend hundreds of dollars in their pockets.
