The new crown pneumonia epidemic is a major public health emergency with the fastest spread, the widest range of infections, and the most difficult prevention and control since the founding of New China. It is a crisis and a big test for China. The Communist Party of China and the Chinese government have attached great importance to it and acted quickly. General Secretary Xi Jinping personally directed and deployed, commanded the overall situation, and made decisive decisions, which strengthened the confidence, pooled strength, and pointed the direction for the Chinese people in fighting the epidemic. Under the leadership of the Communist Party of China, the country has implemented the general requirements of “firm confidence, mutual assistance, scientific prevention and control, and precise policy implementation” to start the people's war, overall war, and deterrence war against the epidemic. After arduous efforts, China paid a huge price and sacrifices to effectively reverse the situation of the epidemic. It took more than a month to initially contain the spread of the epidemic, and it took about two months to control the number of new cases in the country every day to single digits. Within three months, decisive results were achieved in the defense war in Wuhan and Hubei, and major strategic results were achieved in the epidemic prevention and control war, which safeguarded people’s lives and health, and contributed to the maintenance of regional and world public health security. Made an important contribution.
