The author of How Confucius was Tempered has completely and truly restored a vivid Confucius for readers from different angles, such as the growth of saints, Confucius University and standing at the age of 30. At the same time, the book points out that Confucius was born in poverty and was originally a grassroots intellectual. He eventually became a "teacher of all ages" and a "saint of Confucius" admired by all, telling everyone that "saints are tempered by mortals". It also shows people how a real Confucius cultivated from a mortal to a saint, and how he used his life's unremitting efforts to inspire a great nation to revive.
