Some Quotes from Mao's Little Red Book

Chapter 13 --- Relations Between Officers and Men

Our army has always had two policies. First, we must be ruthless to our enemies, we must overpower and annihilate them. Second, we must be kind to our own, to the people, to our comrades and to our superiors and subordinates, and unite with them.

Communists must use the democratic method of persuasion and education when working among the laboring people and must on no account resort to commandism or coercion. The Chinese Communist Party adheres to this Marxist-Leninist principle.

Our comrades must understand that ideological remolding involves long-term, patient and painstaking work, they must not attempt to change people's ideology, which has been shaped over decades of life, by giving a few lectures or by holding a few meetings. Persuasion, not compulsion, is the only way to convince them. Compulsion will never result in convincing them. To try to convince them by force simply won't work. This kind of method is permissible in dealing with the enemy, but absolutely impermissible in dealing with comrades or friends.
