On December 11, Dawan District Science Forum opened in Guangzhou. As one of the sub forums, the life sciences sub forum invited Zhong Nanshan, academician of the Chinese Academy of Sciences, to address the conference. Zhong Nanshan mentioned that he is absolutely confident that the vaccine injection rate will reach 83% by the end of the year. Zhong Nanshan mentioned that he extended a warm welcome to everyone on behalf of Guangzhou National Laboratory. "Many experts and academicians will actively participate in the exchange at this sub forum. You can listen to their wonderful speeches later." This COVID-19 has been two years. Zhong Nanshan took two young people who discovered the structure of DNA in 1953 and later won the Nobel Prize as an example and mentioned that it was a historic discovery at that time. Since then, related developments have accelerated. He said that we should remember the contributions made by our predecessors so many years ago.
