Xinjiang people stay in hotels in the mainland and swipe their ID cards. Can Xinjiang know?

Of course. Because Xinjiang people stay in hotels in the mainland, when they swipe their ID cards, the records will be online at the same time and can be found all over the country, so they can also be found in Xinjiang. Although it can be found, the public security will not help, because it is related to the privacy of citizens, unless it is related to the case.
