It should be "The Four Precepts of the World", an educational book on cultivating morality and establishing destiny, cultivating oneself and governing the world. The author was Yuan Huang in the Ming Dynasty, whose courtesy name was Kunyi and later changed his name to Fan. He wrote it at the age of sixty-nine. The full text is divided into four parts. The author uses his own personal experience to describe the process of changing his destiny. It was originally intended to teach his own son, so he named it "Xun Zi Wen". Later, he changed his name to enlighten the world. "Liaofan's Four Precepts", although they are called "Four Precepts", are actually a "life-establishing principle" that is integrated in one go. It is indeed the "principle of wisdom" in life. "Liaofan's Four Trainings" are the essence of Mr. Yuan Liaofan's lifelong practice of "Tai Shang Induction".
