BEIJING —When Shanghai began its draconian COVID-19 lockdown two months ago, the French restaurant where Sun Wu waited tables closed and the 22-year-old, like countless other rural migrants, lost his job.
To make ends meet, Sun helped sort deliveries for residents under lockdown, earning 250 yuan ($38) a day and moving from a dormitory to live in the warehouse where he worked as required by COVID-19 rules.
