Among those at the forefront of China's battle against COVID-19 is Dong Fang, an ICU doctor that has taken the great responsibility of leading the anti-epidemic work in a hospital at the center of the most-affected city in the country, Wuhan.

ICU work is extremely stressful, highly intense, and dangerous as well. And the protective suits for the medical staff makes the work even harder.

Families of COVID-19 patients are not allowed to visit the patients. So, doctors need to spend some time communicating with those family members after work. As the director of the Critical Care Department at Wuhan No. 3 Hospital, Dong races against time every day to save patients. Dong's husband, also a doctor, was infected with the virus at work. It has been 40 days since they last met each other face-to-face.
