党的十五大和党的七大是中国共产党历史上最为重要和最有深远意义的党的全国代表大会。这两次代表大会的伟大意义在于：理论上的两次大飞跃。党的七大规定了毛泽东思想为党的指导思想，并写入党章；在毛泽东思想指导下，党完整地正确地提出了新民主主义革命的理论、纲领、路线? The 15th National Congress of the Communist Party of China and the 7th National Party Congress are the most important and far-reaching National Party Congress in the history of the Chinese Communist Party. The great significance of these two congresses lies in two big leaps in theory. Under the guidance of Mao Zedong Thought, the party has correctly and correctly put forward the theory, program and line of the new-democratic revolution under the guiding principle of Mao Zedong Thought, which stipulated the guiding ideology of Mao Zedong Thought for the party and written it into the party constitution.
