Abstract: As a significant indicator of national soft power, ideological work is critical to China's national security and social stability in the new era. The Sixth Plenary Session of the 19th Central Committee of the Communist Party of China judges that China's ideological work is witnessing a sweeping and fundamental shift. Based on this judgment, this paper aims to expound this ideological shift by presenting its new forms, the logic of its development and our experience in carrying out ideological work. In terms of forms, we have more scientific management of ideological work, with better institutions and up-to-date discourse system. In terms of logic, we explore the historical and theoretical development of socialist ideology. In terms of experience, we point out that we must stick to Marxism as theoretical basis, and draw inspiration from excellent Chinese culture to carry on the great struggle in developing socialist ideology.
