Abstract: The great founding spirit of the Party is the defining symbols that distinguish the Communist Party of China (CPC) from other political parties. The fine traditional Chinese culture is the cultural gene inherent in the great founding spirit of the Party, as well as the rich legacy for the development of the long line of inspiring principles for the Chinese Communists. In the fine traditional Chinese culture, the spiritual traits of seeking truth and upholding ambition, the profound sentiment of serving the country with loyalty and aspiring for common good for all, the dauntless spirit of ceaselessly pursuing self-improvement and discarding the outdated in favour of the new, and the value orientation of regarding the people as the foundation of the country and governing by virtue have provided a continuous nourishment for the formation and development of the great founding spirit of the Party. To carry forward and practice the great founding spirit of the Party in the new era, we need to stay firmly rooted in Chinese culture, enhance public civility, deepen exchanges and mutual learning among civilizations, and enhance the influence and appeal of the great founding spirit of the Party in building cultural confidence and strength, thus composing the spiritual epic of the CPC leading the Chinese people to promote the construction of a strong country and achieve national rejuvenation.
