Chen Wei has a very strong academic ability and a keen eye. It is through her own efforts that she got what she is today. 1988, after graduating from Zhejiang University, Chen Wei was sent to Tsinghua University. Against the opposition of her parents and friends, she insisted on marrying Ma Yiming, who is 12 years older than herself. After Tsinghua graduated, he gave up his million-dollar salary and chose to join the army and enter the Academy of Military Sciences. From June 5 to February 2002, the first SARS patient appeared in Heyuan City, Guangdong Province. On March 6, 2003, the first SARS patient appeared in Beijing.

Chen Wei plunged into the negative pressure laboratory. Fifty days later, she developed a nasal spray to protect the safety of tens of thousands of medical staff. After that, Chen Wei made unremitting efforts to develop the genotype Ebola vaccine, which brought hope to countless African people. In 2020, after the outbreak of COVID-19, Chen Wei began to participate in the research and development of vaccines in COVID-19. As of September 18, 1 1 vaccine has entered the clinical trial stage in China.

Whenever there is a virus outbreak, Chen Wei always rushes to the laboratory for research and development, and forgets to eat and sleep for several months. In the face of the virus, she will be afraid, but she dare not flinch. Because hundreds of thousands of people across the country are waiting for vaccines and hope. She dare not stop, nor can she stop. In her family, because her son misses his mother, he will kiss her when he sees her photo on TV, and his husband always waits for her silently. Her old parents, watching Chen Wei on TV, all choked up and said that their daughter's hair turned white in the past six months after studying in COVID-19.

People like Zhong Nanshan and Chen Wei who serve the country and the people are lucky for hundreds of thousands of us. They gave their lives to their country and walked at the forefront of danger. With them, we will feel at ease and feel that the virus is actually not so terrible. They are our heroes and our guarantee.
