Sanitation workers toil away on the roads to keep things tidy. Cleaning workers disinfect the roads and business areas while wearing masks and gloves as a precaution against the virus.

The Beijing subway and bus operators have increased the frequency of buses and subway trains, limited passenger numbers during rush hours and enhanced disinfection.

These measures will curb the transmission of the virus that might spread during the travel season and guarantee the safety of both workers and their workplaces.
