The level of cultural preservation in Chang Tang far exceeds that of the Western Lands.
As soon as Durin stepped out, he felt the difference between the Western Lands and the Eastern Land in this world.
Although in his past life the Eastern Land was indeed the most advanced, it wasn't nearly as absurd as it is in this world; take for example the bank Durin just entered, where he actually saw an automatic number ticket dispenser—although it appeared to be mechanical, all you really had to do was insert something like an identity document, and it would spit out a card for you.
This was good news.
The bad news was that Durin didn't have any proof of identity.
However, fortunately, the horns on Durin's head served as his identification.
