Passengers wearing masks to protect from the coronavirus wait for their train at the South Train Station in Beijing, China, Friday, Jan. 14, 2022. As the Beijing Winter Olympics loom, the Chinese capital is stepping measures to keep the coronavirus at bay including suspending most access to Tianjin, an adjacent major city which is dealing with an outbreak of the highly contagious omicron variant. These outbreaks are posing a test to its "zero-tolerance" COVID-19 policy and its ability to successfully host the Winter Olympics. (AP Photo/Ng Han Guan)
