Abstract: “Happiness is the result of struggle”, this is Xi Jinping’s earnest hope for young people in the new era, and it is also the theoretical basis for young people in the new era to understand happiness, obtain happiness and enjoy happiness. The spirit of struggle is not abstract and mysterious, but concrete and practical. The logical way to cultivate the spirit of youth struggle in the new era is to clarify the fundamental issues of “what is the spirit of struggle”, “why should we cultivate the spirit of struggle” and “how to cultivate the spirit of struggle”, and to educate and guide young people in the new era in realizing the great cause of national rejuvenation. To work in unity, we must continue to struggle in tempering our will and creative practice, we must work hard without forgetting our original intentions, and we must work hard while taking responsibility and training our skills.
