<span>Throughout the ages, there are numerous tacticians but Sima Yi has been widely criticized because modern people's opinions on him are derived from the historical fictions, especially Romance of the Three Kingdoms. For the role of Sima Yi, the official history only says ''he always comes out with great ideas and strategies''. Growing from a grass-roots official of Eastern Han into a powerful minister of Kingdom Wei, he was the actual founder of Western Jin and another hero who came to the throne with military exploits after Cao Cao in Chinese history. It can be said that he was a winner in the Three Kingdoms and one of the seriously underestimated and distorted counselors and politicians in history. From the perspective of human nature and taking the real complex political situations in Three Kingdoms as the background, the book tells how the powerful ministers and counsellors represented by Sima Yi survived in the court, behaved in the society and made psychological attacks in the political situations of taking cities and seizing territory with no battle. Through Sima Yi, readers can see the unique survival philosophy of traditional Chinese officialdom, look into the living conditions of individuals and comprehend the wisdom of life.</span>
