一切忠诚、坦白、积极、正直的共产党员团结起来，反对一部分人的自由主义的倾向，使他们改变到正确的方面来。这是思想战线的任务之一。 - Mao Zedong

The revolutionary red guards and revolutionary student organizations must form a grand alliance. As long as they are revolutionary mass organizations, they must form a great alliance according to revolutionary principles.

Active defence is also known as offensive defence, or defence through decisive engagements. Passive defence is also known as purely defensive defence or pure defence. Passive defence is actually a spurious kind of defence, and the only real defence is active defence, defence for the purpose of counter-attacking and taking the offensive. As far as I know, there is no military manual of value nor any sensible military expert, ancient or modern, Chinese or foreign, that does not oppose passive defence, whether in strategy or tactics. Only a complete fool or a madman would cherish passive defence as a talisman.

下定决心，不怕牺牲，排除万难，去争取胜利。
