The anti ? epidemic spirit is tempered by the inheritance and development of Marxism，the excellent traditional culture of the Chinese nation，and the practice of the Chinese people in fighting the COVID ? 19 pandemic. It is a great spiritual culture in line with China’s revolutionary spirit and core values of socialism. Its influence on social morality is reflected in the promotion of truth?seeking style，arousing the sense of responsibility for youth’s mission，promoting the formation of a social morality of solidarity and cohesion， strengthening people’s cultural and national self ? confidence，and improving the construction of spiritual civilization. We need to further develop the positive influence of the anti ? epidemic spirit on social morality. Specific suggestions include integrating anti ? epidemic culture into ideological and political education， strengthening the spiritual characteristics of contemporary youth，and strengthening the construction of socialist spiritual civilization.
