On February 15, 1945, Mao Zedong spoke about shantou zhuyi (山头主义), “mountaintop-ism,” in which each group in the Party holds to its own hill. He did not deny that such groups existed. “Acknowledging that mountaintop-ism exists,” he said, “has the purpose of eliminating the mountaintops, so that they melt together and the whole Party becomes one body.”
