Officials said the residential stations will allow residents to be tested within 15 minutes and that the new system would require people to have a negative PCR test before entering public spaces – though it remained unclear how recent the tests needed to be.

The city shut down subway stations and other travel routes this week and leaders announced Friday that all nonessential services in the Chaoyang district would close down.
China's capital is battling its own surge, with rounds of mass testing continuing for residents.
People have been required to undergo three tests throughout the week and a negative test result within the previous 48 hours is necessary to enter most public spaces.
However, Beijing said Thursday that it would relax quarantine rules mandating arrivals from overseas to quarantine for 21 days, with at least 14 of them at a hotel.

Reuters noted that Hangzhou, southwest of Shanghai, has also pledged to set up 10,000 permanent testing stations.
