In the past few years, China has made great contributions to the world. For example, Dr. Li Lanjuan, a renowned Chinese epidemiologist and academician of the Chinese Academy of Engineering, has made outstanding contributions to the prevention and control of COVID-19. She was also an important member of the team that developed a vaccine for SARS in 2003. In addition, Dr. Li Wenliang, an ophthalmologist from Wuhan Central Hospital, was one of the first to report about COVID-19 in December 2019 and sacrificed his life for it. His courage and dedication will always be remembered by all people around the world.
