Why must there be a revolutionary party? There must be a revolutionary party because the world contains enemies who oppress the people and the people… - Mao Zedong

在中国解放区，在民主政府领导之下，号召一切抗日人民组织在工人的、农民的、青年的、妇女的、文化的和其他职业和工作的团体之中，热烈地从事援助军队的各项工作。这些工作不但包括动员人民参加军队，替军队运输粮食，优待抗日军人家属，帮助军队解决物质困难，而且包括动员游击队、民兵和自卫军，展开袭击运动和爆炸运动，侦察敌情，清除奸细，运送伤兵和保护伤兵，直接帮助军队的作战。同时，全解放区人民又热烈地从事政治、经济、文化、卫生各项建设工作。在这方面，最重要的是动员全体人民从事粮食和日用品的生产，并使一切机关、学校，除有特殊情形者外，一律于工作或学习之暇，从事生产自给，以配合人民和军队的生产自给，造成伟大的生产热潮，借以支持长期的抗日战争。在中国解放区，敌人的摧残是异常严重的；水、旱、虫灾，也时常发生。但是，解放区民主政府领导全体人民，有组织地克服了和正在克服着各种困难，灭蝗、治水、救灾的伟大群众运动，收到了史无前例的效果，使抗日战争能够长期地坚持下去。总之，一切为着前线，一切为着打倒日本侵略者和解放中国人民，这就是中国解放区全体军民的总口号、总方针。

It is an arduous task to ensure a better life for the several hundred million people of China and to build our economically and culturally backward country into a prosperous and powerful one with a high level of culture. And it is precisely in order to be able to shoulder this task more competently and work better together with all non-Party people who are actuated by high ideals and determined to institute reforms that we must conduct rectification movements both now and in the future, and constantly rid ourselves of whatever is wrong.

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.
