There are presently about 4 million migrant workers in Shanghai https://journals.openedition.org/chinape...the%20city.

It is very likely these workers will come back if Shanghai's life returns back to normal in the near future.   Understand the Covid situation has turned better but there are still pockets and areas under lockdown because of scattered covid infections reported in the city.  Shanghai residents are still waiting for life to return back to normal.
