Tianjin will start its weekly COVID-19 test requirement in a bid to keep the virus in check from Aug 22, authorities announced on Sunday.
Citizens without a record of a nucleic acid test from within seven days will be assigned a yellow code on Tianjin health code system, the official notice said. A yellow code restricts access to some public venues.
Citizens can download the "Tianjin Digital Epidemic Prevention" APP to find nearby sampling points for free nucleic acid testing, use QR codes to collect nucleic acid samples, check test results, vaccination status, and show health codes when entering public places.
