Epidemic prevention and control measures were immediately tightened.
The municipal urban administration bureau led relevant environmental sanitation departments to disinfect key areas and main roads in the city.

Inspection teams were deployed at the airport, railway stations and expressway toll gates for checking the COVID-19 negative certificates.
