Xu Gang, a 45-year-old bus driver from Fushun City, northeast China's Liaoning Province, takes pride in serving his country through his job. A video of him offering a face mask to an old man on his bus recently went viral, grabbing substantial media attention in the country. Public transport employees come under the COVID-19 high-risk group, but they have fearlessly discharged their duties. Xu told CGTN that being a man of responsibility is the part that he enjoys the most about his profession.
