To effectively prevent imported cases, Zhongshan citizens who want to enter indoor public places or residential areas are required to present a valid negative nucleic acid test result or a test record for three consecutive days from April 11.

In the early morning, citizens lined up for the testing. All towns and districts set up more sampling sites and extended the service hours to ensure an orderly and efficient testing.
