To prepare the 3,000-plus orders of vegetables, meat and essentials her Carrefour supermarket sends out every day to locked-in Shanghai residents, manager Zhang Wei wakes at 5 a.m. after a night in a sleeping bag on her office floor.
Zhang and 43 colleagues have been hunkered down inside the store in Shanghai's western Xujing suburb since April 1, isolated from the outside world while working long days to fill online orders from neighbouring housing compounds.
