On this day, 75 years ago, September 10, 1950 (July 28, 1950, the lunar calendar), Liu Shaoqi emphasized the importance of building the ruling party's government. On September 10, 1950, Liu Shaoqi delivered a speech at the opening ceremony of Classes 2 and 3 of Marxism-Leninism College. Liu Shaoqi emphasized the importance of theoretical study and talked about the correct attitude and correct method of learning. Liu Shaoqi said: The China revolution has won. Overall, we have done a good job in all aspects of our work, but theoretical work is a very weak link. Many of our cadres, even senior cadres with important responsibilities, have rich experience in struggle, but their theoretical level is not high. This is a weakness of our party. Now, one of our important tasks is to improve the cultural and theoretical level of cadres. This is a regular task. There is certainly a danger of dogmatism when there is only theory without practice, but theory is the guide for practical work. Without theory, work is blind and has no future. People without theories are easily "captured" and confused by other people's extravagant words. Only by mastering theory can we correctly guide work. Regarding learning methods, Liu Shaoqi pointed out that when we study Marxism-Leninism, we must study its positions, viewpoints, and methods, and not turn Marxism-Leninism into dogma. The problems you will encounter and deal with in the future are all new problems, many of which Marx, Engels and Lenin did not mention. They haven't talked about it, how to deal with it? You have to use the positions, viewpoints, and methods of Marxism-Leninism you have learned to observe, analyze, and deal with it well. This is called having some theories. When talking about learning attitudes, Liu Shaoqi emphasized that the more theoretical knowledge people have, the more they should feel that they know less. If you learn some Marxism-Leninism, you will not be more humble but more proud, which means that you have not learned the most important thing in Marxism-Leninism. Our comrade's work style must be upright, and we must remove any flaws. We should realize that we are under the leadership of the party and do everything for the party and the people. This cognitive problem should be completely solved. After learning Marxism-Leninism, we must overcome individualism, liberalism, commandism, and bureaucracy.
