In the Three Kingdoms era when heroes abounded, the reason why Sima Yi stood out was that the essence of his wisdom in life lay in the word "forbearance", which meant he could endure what ordinary people could not endure. Through "forbearance", he waited for the opportunity and chose Mingzhu; through "forbearance", he acted cautiously and faithfully and won trust; through "forbearance", he was shy and cautious and defeated the wise people; through "forbearance", he paralyzed his opponent, fought back and seized power. With a popular, delicate and cold writing style, this book attempts to go through the fog of history, reveal Sima Yi's political logic and philosophy behind many political events, express his loyalty and rebellion, and depict his life that is different from traditional facial makeup.
