Knotting his brows at some medical reports，one old man sensed a potential danger.On that day，59 citizens in Wuhan had caught pneumonia （肺炎） of unknown etiology.The phenomenon reminded him of the Severe Acute Respiratory Syndrome （SARS） outbreak that had spread across China 17 years ago.It was he who had come up with an effective treatment for SARS.
   China's most respectable epidemiologist （流行病學(xué)家），84-year-old Zhong Nanshan，is widely known to the public as the hero who defeated SARS.After a lifetime researching respiratory diseases，he was keenly aware that the new pneumonia may not be a simple disease，but a Pandora's box that could engulf the world.
   Zhong grew up in a family of doctors，and lives by a simple motto：save lives and always be honest.In 2003，when SARS spread across China，he volunteered to treat patients，staying in hospital wards for weeks on end to study the disease.At the same time，he also spent countless nights in his lab looking for a cure for the deadly disease.His efforts paid off.Months later，his treatment plan for SARS was adopted by China and then the whole world，saving thousands of lives.
   Zhong is also known for an incident.When authorities announced that the virus had been brought under control，he publicly criticized the assessment，deciding instead to tell the public the truth.In one post-SARS interview，he said： "I couldn't help myself.I said it's not all under control." His virtue （美德） won widespread praise from the Chinese public，who hailed him as a hero.
   Seventeen years later，the old man is once again leading a team in a battle.Although this new virus is known to be particularly dangerous to the elderly，Zhong paid little attention to his own safety.On January 29，he and his colleagues spent over six hours on an online medical inquiry，checking five patients who were in critical condition.
   "The hospitals are our battlefield，and doctors and nurses are warriors.When we are needed，we should charge forward，because this is our duty!" said Zhong.
   As well as treating the patients，Zhong is also a messenger who delivers factual updates of COVID-19 to the public.Being unfamiliar with social medical platforms，he has asked colleagues to help him make videos aimed at calming fears about the virus and teaching the public how to prevent the disease，such as how to wash hands or wear a mask correctly.
   While praised as hero，Zhong told the media that Wuhan，the center of China's COVID-19 outbreak and where tens of thousands of citizens have been confined to their homes for weeks to prevent the spread of the disease，also deserves that honor.
