'The twenty years of the Communist Party of China have been twenty years in which the universal truth of Marxism-Leninism has become more and more integrated with the concrete practice of the Chinese revolution. If we recall how superficial meagre our understanding of Marxism-Leninism and of the Chinese revolution was during our Party's infancy, we can see how much deeper and richer it is now. For a hundred years, the finest sons and daughters of the disaster-ridden Chinese nation fought and sacrificed their lives, one stepping into the breach as another fell, in quest of the truth that would save the country and the people. This moves us to song and tears. But it was only after World War I and the October Revolution in Russia that we found Marxism-Leninism, the best of truths, the best of weapons for liberating our nation. And the Communist Party of China has been the initiator, propagandist and organizer in the wielding of this weapon. As soon as it was linked with the concrete practice of the Chinese revolution, the universal truth of Marxism Leninism gave an entirely new complexion to the Chinese revolution. Since the outbreak of the War of Resistance Against Japan, our Party, basing itself on the universal truth of Marxism-Leninism, has taken a further step in its study of the concrete practice of this war and in its study of China and the world today, and has also made a beginning in the study of Chinese history. These are all very good signs. However, we still have shortcomings, and very big ones too. Unless we correct these shortcomings, we shall not, in my opinion, be able to take another step forward in our work and in our great cause of integrating the universal truth of Marxism-Leninism with the concrete practice of the Chinese revolution.'
