When Beijing research institute employee Terry Xu first started using an app called CoSleep to help him get a good rest, it was to help deal with the stress of looking for a job about three years ago after graduating from university.
“With the Covid-19 pandemic in China recently getting worse, I would browse what people post on social media and often stay up late,” Xu said in a phone interview on Thursday. “Now I’ve started to use CoSleep more frequently.”
