BEIJING, CHINA - MAY 04: A traveller sits with his bags in from of the locked gate of a subway station due to a concern of the spread of COVID-19 on May 4, 2022 in the Central Business District in Beijing, China. Beijing closed dozens of metro stations Wednesday after tracing showed that a resident who tested positive for COVID-19 had travelled on numerous routes of the city's metro system. China is trying to contain a spike in coronavirus cases in the capital Beijing after dozens of people tested positive for the virus in recent days, causing local authorities to initiate mass testing in most districts, close schools, and ban gatherings and inside dining in all restaurants, and to lockdown some neighbourhoods in an effort to maintain the country's zero COVID strategy.
