The camera hovers just above the elderly woman's head, as she looks up, her face becomes confused and worried.

"Yes auntie, this is the drone speaking to you," a voice booms out. "You shouldn't walk about without wearing a mask."
The woman hurries off, occasionally looking over her shoulder as the drone continues to shout instructions: "You'd better go back home and don't forget to wash your hands."

This is China under quarantine in 2020. In another video promoted by state media, a police drone orders men sitting at an outdoor mahjong table to "stop playing and leave the site as soon as possible."
"Don't look at the drone," it says, as a small child glances up curiously. "Ask your father to leave immediately."

As Chinese authorities struggle to contain the deadly Wuhan coronavirus, they are turning to a sophisticated authoritarian playbook honed over decades of crackdowns on dissidents and undesirables to enforce quarantines and lockdowns across the country.

I only hope it's handlers don't pick up the virus from the drone
