For example, just like him. The ancients said that a saint has three criteria: meritorious service, virtue and speech, which are immortal, and they are collectively called "saints". Meritorious service refers to people who have made great contributions to society, country and people. Dayu, who was in charge of water conservancy, Wei Qing, who attacked Xiongnu in the north, and Yue Fei, a famous gold fighter, were all called "meritorious deeds". Lide means to establish moral standards for the world and has far-reaching influence. From Confucius and Mencius' benevolence, righteousness, courtesy, wisdom and faith to Kong Rong's Li Luo's honest official Hai Rui, they can all be called "Lide". To establish a theory is to write a book and establish one's own academic school, with many learners. During the Spring and Autumn Period, a hundred schools of thought contended, and Confucius and Mencius, Laozi and Zhuangzi, Han Fei, Mozi and Zhu, a Neo-Confucianism in the Song Dynasty, could all be called "opinions". It's not easy to be one of the Three Immortals. It can be called a "great man" or a "celebrity". If a person has achieved all three immortals, can he still be called a "saint"? Today, I'd like to introduce you to a man who has achieved all three immortals: Wang Yangming (or Wang Shouren), founder of Mind Studies in the Ming Dynasty, thinker, writer, philosopher, strategist, official to the history of the Ministry of War, and posthumous title Wenchenggong.
