Zhang Hewu, an 82-year-old respiratory specialist at Wuhan Pulmonary Hospital, returned to his post on Monday after 157 days of being treated for COVID-19.
At the beginning of 2020, Zhang plunged into the front line of the fight against the epidemic, and unfortunately became infected by the coronavirus.
During his hospitalization, he came close to death due to respiratory failure and wrote a thick self-diagnosis medical record for medical staff. He often said, "My biggest wish is to get back to work as soon as possible."
