When the man from Hangzhou returned home from a business trip, the local police got in touch. They had tracked his car by his license plate in nearby Wenzhou, which has had a spate of coronavirus cases despite being far from the epicenter of the outbreak. Stay indoors for two weeks, they requested.
After around 12 days, he was bored and went out early. This time, not only did the police contact him, so did his boss. He had been spotted near Hangzhou's West Lake by a camera with facial recognition technology, and the authorities had alerted his company as a warning.
"I was a bit shocked by the ability and efficiency of the mass surveillance network. They can basically trace our movements with the AI technology and big data at any time and any place," said the man, who asked not to be identified for fear of repercussions.
