Who are our enemies? Who are our friends? This is a question of the first importance for the revolution.

It is good that since the outbreak of the war with Japan, more and more revolutionary writers have been coming to Yan'an...

The guerrilla must move amongst the people as a fish swims in the sea.

The arrow of Marxist-Leninism must be used to hit the target of the Chinese Revolution.

...it is impossible for a genuine people's revolution in any country to win victory without various forms of help from the international revolutionary forces.

Passivity is fatal to us. Our goal is to make the enemy passive.
