An example: after security guards found a woman's qr code vaccine passport turned to red which means she contacted with someone who tested positive last 14 days,this supermarket was in lockdown immediately!
All people trapped must do covid test
Negative you leave if not stay!
When people heard about one customer's qr code vaccine passport turned to red,they rushed to exit to escape from lockdown and later covid test before security guard locked this shopping mall up in Beijing China
Guangdong province dongguan city Walmart supermarket
Chinese people's the worst nightmare comes true!
One customer's qr code vaccine passport turned to red. This Walmart is in lockdown immediately!
All customers are being locked in and sleep here & wait for covid test.
