Both sides engaged in an extensive propaganda war in an attempt to enlist community support. Central authorities in Beijing eventually endorsed the Worker's Headquarters faction as the "true" revolutionary group and reprimanded Chen Zaidao for his military support to Million Heroes.

Fears of a more widespread PLA revolt led Mao and his core associates to scale back the movement's most radical components.
