Gu Yong Su is a doctor and the CEO of The Miin Clinic in South Korea. After the COVID-19 outbreak in the country, a drive-thru testing clinic was set up and doctors were urgently needed. Dr. Gu applied without hesitation. The clinic tested about 34 people per hour and things were quite busy. As an experienced doctor, Gu took the responsibility of sampling, which is seen as one of the most dangerous tasks during the testing process. Once in protective gear, Dr. Gu has to work for at least 4 hours and cannot drink or use the restroom. Still, he does not consider himself a hero.
