The COVID-19 epidemic was a disaster. But not so, mankind surrendered. Vietnam is a leading country in the control of epidemics. And we - the students also play a big part. To prevent SARS-CoV-2, we always follow the 5K principle set by the Ministry of Health. We always wear masks when we go out, don't gather people, report medical in school and on smart apps Bluezone. When we go home, the first thing we do is wash our hands. When we reach a crowded place, we always pay attention to the distance from everyone, standing as far apart as possible. All for a better world. May the epidemic end soon, restore peace to mankind.
