Jiang Qing promoted the idea that the Red Guards should "crush the PLA,"[citation needed] with Lin Biao seemingly supportive of her plans (e.g., permitting Red Guards to loot barracks). At the same time, several military commanders, oblivious to the ongoing chaos that the People's Liberation Army (PLA) had to deal with, disregarded their chain of command and attacked Red Guards whenever their bases or people were threatened. When Red Guards entered factories and other areas of production, they encountered resistance in the form of worker and peasant groups who were keen to maintain the status quo.[1] In addition, there were bitter divisions within the Red Guard movement itself, especially along social and political lines.
