In Xinjiang, authorities have created a system that considers individuals suspicious based on broad and dubious criteria, and then generates lists of people to be evaluated by officials for detention. Official documents state that individuals “who ought to be taken, should be taken,” suggesting the goal is to maximize the number of people they find “untrustworthy” in detention. Such people are then subjected to police interrogation without basic procedural protections. They have no right to legal counsel, and some are subjected to torture and mistreatment, for which they have no effective redress, as we have documented in our September 2018 report. The result is Chinese authorities, bolstered by technology, arbitrarily and indefinitely detaining Turkic Muslims in Xinjiang en masse for actions and behavior that are not crimes under Chinese law.

> The IJOP system also alerts officials when people are using phones that do not belong to them, giving the officials information about the case and the personal particulars of the person who is registered to the phone account, such as their ID number (see screen 19). It is unclear how the system “knows” that a person is using a phone that does not belong to them.[80] Officials are again required to log the reasons for the mismatch and decide if the person is suspicious.[81]
This technique especially scary for people concerned about privacy, because it means passive attempts to avoid surveillance will invite more direct invasions.
Many—perhaps all—of the mass surveillance practices described in this report appear to be contrary to Chinese law.
Of all the articles about Xinjiang and Chinese human rights issues, this is one of rare ones that's right up HN's alley, because of its focus on the details of the technology of mass surveillance.

Or are you talking about the Great Firewall, which unsurprisingly appears to be blocking the Human Rights Watch website:
