Videos of what appears to be a drone flying in the sky, broadcasting instructions for residents quarantined due to Corona, spread on Twitter and the Chinese social networking platform Weibo.

One clip shows a drone with flashing red lights hovering over apartment buildings in Shanghai, China, loudly transmitting messages: "Everyone... don't sing on your balcony. It increases the risk of transmission... You have to control the desire for freedom."

This video monitors the anger of the residents in the balconies because of the stone.

When people start to bang their pots and scream “we want supplies” you know its not the Shanghai you used to know.

In other clips, drones were seen broadcasting messages to college students that due to the closure restrictions, one must maintain face masks at all times and stay within the confines of college dormitories.

As seen on Weibo: Shanghai residents go to their balconies to sing & protest lack of supplies.

A drone appears: “Please comply with covid restrictions.

Control your soul's desire for freedom.

Do not open the window or sing.”

Videos have also been uploaded to Weibo of a robot dog jogging through the empty streets of Shanghai.

The dog was spotted carrying a loudspeaker through which instructions are given: "You must disinfect regularly. Ventilate your home. To prevent the epidemic in a scientific way."

Full Lockdown in Shanghai, this is how their announcements.

Shanghai is currently grappling with a marked increase in COVID-19 cases, which has pushed the entire city of 26 million people into a strict lockdown amid mandatory mass testing for the virus.

However, the city's "Covid-zero" policy drew criticism after disturbing videos emerged of babies and young children being left unattended in the city's overcrowded quarantine center, a move the Chinese government has defended.

The city's comprehensive testing system has shown more than 94,000 infections in Shanghai since March 1, according to the Chinese newspaper, So.
