I was going to post translations of a few select sections from the book, please excuse my amateurish translation
Perhaps many people will not believe Chinese military is capable of conducting this type of "three all policy[1]", this is completely against PLA's aim of serving the people. People that never participated in war perhaps will never understand, when you see your comrade was fighting shoulder to shoulder with you in one moment, but dead the next; when you have not shut eye after many day and night, fighting in continous raid, fear and hunger; when continous fighting extremely exceeded physical limitation, mind starts to hallucinate, see how long your spirit and heart can cope under fear, paranoia, and confusion. Some fellow soldier have said that they would rather by killed promptly by a bullet than die of exhaustion under those extreme condition. You didn't want to kill those unarmed civilians, but the phycological fear forced you to not able to endure those pressure; when terror is always in your mind, you feel that any living thing will pose a danger to you; when an unit think all grass and tree are solders, you could do something you cannot imagine. Do not know if this is fear, or retaliate, or hallucination, but during the whole war period, intentional or unintentional shotting of comrade and civilians, desertion, self mutalation... those thing that should or should not have happened have occured.
