Mao Zedong said this quote

Politics is war without blood, while war is politics with blood.

~ Mao Zedong

...this protracted war will pass through three stages. The first stage covers the period of the enemy's strategic offensive and our strategic defensive. The second stage will be the period of the enemy's strategic consolidation and our preparation for the counter-offensive. The third stage will be the period of our strategic counter-offensive and the enemy's strategic retreat.

~ Mao Zedong

Our attitude towards ourselves should be to be insatiable in learning and towards others to be tireless in teaching.

~ Mao Zedong

A revolution is not a dinner party, or writing an essay, or painting a picture, or doing embroidery; it cannot be so refined, so leisurely and gentle, so temperate, kind, courteous, restrained and magnanimous. A revolution is an insurrection, an act of violence by which one class overthrows another.

~ Mao Zedong
