The grandeur of the Hexi Corridor largely comes from the movement itself. Treat it as a reading that needs to unfold slowly, rather than a gap between multiple attractions.
Treat the journey as part of the itinerary
In the northwest, the scenery changes with the distance of kilometers. Reserve time by the window; don't rush to fill all the silence with headphones.

In places with high artistic and historical density, half a day is often more meaningful than a rushed hour.
Respect the climate and distance
The comfort of long journeys comes from reliable supplies, suitable clothing, and routes that aren't over-compressed.
