用一段英文描述疫情下的奉献的真实具体事例（提及姓名）

During the coronavirus pandemic, there have been many inspiring stories of people who have gone above and beyond to help others. For example, Dr. Li Wenliang, a doctor in Wuhan, China, was one of the first to sound the alarm about the outbreak of COVID-19. He tirelessly worked day and night to diagnose and treat patients in his hospital despite being reprimanded by local authorities for doing so. Sadly, he passed away from the virus in February 2020, but his selfless act of courage will never be forgotten.
