People are seen to shop in an orderly fashion at Shanghai's Costco store on Feb 23. There was no overcrowding on Sunday as strict measures such as temperatures being taken, warning signs and one-way access to the food court designed to prevent a possible COVID-19 spread. The road outside the supermarket remains crowded and many vehicles are parked on the opposite side of the road to the supermarket. Customers have to cross the road to enter the store.
