Residents of Hong Kong gather in a shopping mall atrium on a Sunday during the Covid-19 pandemic. To tackle Covid-19, the Hong Kong government has enforced by law to prohibit group gatherings of more than four persons in public places; therefore, every group of people maintained a minimum 1.5 meter ‘social distance’ from another group of people. The man with the lanyard around his neck is a compliance officer enforcing the 1.5 meter-minimum social distancing rule.
