That's the Chinese way eh? Literally using facial recognition scanners to track where people are, reporting whereabouts to the communist party (this is done all the time too, as you have to use your ID card like literally everywhere and the employees are obligated to note down all this info) Literally just following the people at every turn, and ensuring that every single one of them listens to the government.
