“Comprised of rows of three-story buildings topped with gray roofs in traditional Chinese style, the massive complex spans an area the size of 46 football fields and took less than three months to be built from scratch on the outskirts of the city.

It will replace designated hotels located throughout Guangzhou to quarantine Chinese and international travelers arriving from overseas — a move aimed at reducing residents’ exposure to imported cases.
Travelers will be transferred on buses directly from the airport, and confined to their rooms for at least two weeks. Each room is fitted with a video chat camera and an artificial intelligence-powered thermometer, with three meals a day delivered by robots — all designed to minimize direct contact with staff members.”
