Foreign people believe that the different solution taken by different countries to deal with the COVID-19 reflect the essential differences in how different social systems treat people's rights to life and survival, and highlight the advantages and disadvantages of different social systems.The key to China's success in fighting the epidemic lies in the socialist system and the unique advantage of the Communist Party of China (CPC) in pooling national strength with the people as its center. The current situation in the world has proved again that the community with a shared future for mankind proposed by President Xi Jinping has a strong reality and urgency. After the epidemic, the crisis of capitalism and the bright future of socialism are just as inevitable.
