Prosperity and development of a strong military culture - create a new great cause with new great struggle. "The soul of the people is shaped by culture; the spirit of the country is shaped by culture." A nation without cultural self-confidence can hardly win dignity and self-reliance, and an army without cultural self-confidence can hardly achieve reform and self-improvement. In his report to the Twentieth National Congress of the Communist Party of China, President Xi profoundly clarified the role of culture in the new era and new journey, clarified the major task of "promoting cultural self-confidence and self-improvement, and creating a new glory of socialist culture", and emphasized the need to "prosper and develop a strong military culture". This not only sounded the clarion call for accelerating the construction of a socialist cultural power, but also issued a mobilization order for strengthening and improving the military cultural construction of our army in the new era. We should closely focus on the Party's goal of building a strong military in the new era, prosper and develop a strong military culture that has our own characteristics, reflects the spirit of the times, and supports winning. We should sow loyalty, cultivate faith, stimulate blood, and inspire morale on the spiritual and cultural highlands, and lead officers and soldiers to fight to the forefront of the times, providing a strong guarantee for the realization of the Chinese dream of building a strong military. "Soldiers take martial arts as their plant and culture as their seed. Martial arts are their surface and culture as their core." If weapons and equipment are the bones and muscles of an army, culture, as a soft power, forges the spirit of an army and nourishes its soul. In the long-term practice of revolution, construction and reform, our army has formed a lofty "cultural gene" and a hero's "cultural blood", which has become the most distinctive spiritual banner in the development and expansion of our army. Since the 18th National Congress of the Communist Party of China (CPC), under the guidance of President Xi's important strategic thought of "building a strong military culture", the whole military at all levels has closely focused on realizing the Chinese Dream and the dream of building a strong military, constantly prospered and developed military cultural construction, insisted on using the latest theoretical innovation achievements of the Party to gather souls, cultivate revolutionary soldiers in the new era of "four haves", forge "four irons" excellent troops, and shape the Chinese heart, national spirit and strong military ambition of the whole military, The cultural creativity of regrouping and starting again provides a strong spiritual strength and a strong ideological guarantee for the PLA to reshape its political ecology, organizational form, power system and style of work. Practice has shown that the culture of building a strong military is a distinctive symbol of the advanced military culture of our military in the new era, and an internal support for unswervingly pursuing the path of building a strong military with Chinese characteristics. It is urgent and timely to prosper and develop the culture of building a strong military. What banner to hold determines the direction of cultural development. The progressiveness nature of culture lies in the progressiveness and scientific nature of its guiding ideology. Adhering to the use of Marxist theory and its latest achievements to firmly occupy the cultural front is the fundamental guarantee for our army to maintain the nature of the people's army and the correct political direction, as well as the primary prerequisite for the prosperity and development of a strong military culture. Marx said: "If we look at it from the perspective of ideas, the disintegration of a certain ideology is enough to destroy the entire era." Only by adhering to the guiding position of Marxism can we adhere to the correct direction of the prosperity and development of a strong military culture. At present, the struggle in the field of ideology is becoming increasingly severe and complex. The officers and soldiers of the "Cyber Generation" have distinctive personalities and active thinking, but they are often vulnerable to adverse social trends because of their lack of experience.
