Who will pay for the quarantine 14 days in Datong city?

Under normal circumstances, they are at their own expense.

Generally speaking, whether you come back from abroad or go back and forth between domestic cities, you need to bear the costs of being isolated because of the epidemic (nucleic acid testing costs, accommodation, meals, transportation, etc.). ), and this situation needs to be borne by yourself. If the government forces isolation, the expenses incurred in hotel isolation shall be borne by the government. The epidemic isolation fee is not free in all places, and each region has its own policy, and many places bear it themselves, so it depends on local regulations.
