It was a time of breakthroughs and transform ations. As time passed and the gun was fired on the famous Russian cruiser called Aurora, the Marxism-Leninism that had been transported to China took root in the country’s fertile soil where it sprouted and blossomed. There, it flourished in all magnificence and produced a Chinese theory that was unique, rational, and appropriate. This Chinese theory, which is in line with Marxism-Leninism and Mao Zedong Thought, is guiding China towards historic achievements and fundamental changes and creating an Eastern miracle that reflects the saying, "The landscape here is beyond compare." As socialism with Chinese characteristics has entered a new era, we are concentrating on building a modern socialist power that is prosperous, strong, democratic, culturally-advanced, harmonious, and beautiful, and bringing about the Chinese Dream of national rejuvenation. In this situation, it is even more important not to forget the "ancient ancestors".In other words, we must continue to adhere to the theoretical system of socialism with Chinese characteristics and increase our confidence in this theory.
