This book does not write about the "perfect saint", but only about the "idiot Zeng Guofan" - he experienced the depression of failing to pass the exam, the obstacles in the workplace, and the despair of defeat in the army, but with "sincerity", "self-discipline" and "persistence", he got out of the quagmire step by step. The core of the final message is: The so-called success does not depend on talent, but on taking simple principles to the extreme and using stupid methods into unique tricks, so that every ordinary reader can find his own courage to counterattack from his story.
