FILE - In this April 15, 2020, file photo, workers in full protective gear stand in a parking lot of the West Station in Beijing, China, as part of the team coordinating quarantine for incoming passengers from Wuhan. Getting into Wuhan was the easy part as new infections had fallen to almost zero and travel restrictions were relaxed. As a 76-day lockdown neared its end, journalists were allowed to return to the Chinese city where the coronavirus pandemic originated. But getting out was proving harder. The bureaucracy had yet to finalize how people would safely organize their return and three official documents were needed: A green health code, home neighborhood approval and a recent nucleic acid test.
