Guard movement had waned over the course of the preceding year, violence by the remaining militant Red Guards increased on some Beijing campuses. Violence was particularly pronounced at Qinghua University, where a few thousand hardliners of two different factions continued to fight. At Mao's initiative, on July 27, 1968, tens of thousands of workers entered the Qinghua campus shouting slogans in opposition to the violence. Red Guards attacked the workers, who continued to remain peaceful. Ultimately, the workers disarmed the students and occupied the campus. On July 28, 1968, Mao and the Central Group for the Cultural Revolution met with the five most important remaining Beijing Red Guard leaders to address the movement's excessive violence and political exhaustion.

A notable example was the "mango fever." On August 4, 1968, Mao was presented with about 40 mangoes by the Pakistani foreign minister, Syed Sharifuddin Pirzada, in an apparent diplomatic gesture. Mao had his aide send the box of mangoes to his Mao Zedong Propaganda Team at Tsinghua University on August 5, the team stationed there to quiet strife among Red Guard factions. On August 7, an article was published in the People's Daily saying: In the afternoon of the fifth, when the great happy news of Chairman Mao giving mangoes to the Capital Worker and Peasant Mao Zedong Thought Propaganda Team reached the Tsinghua University campus, people immediately gathered around the gift given by the Great Leader Chairman Mao. They cried out enthusiastically and sang with wild abandonment. Tears swelled up in their eyes,
