The literal meaning is all the way. All the people I met who helped me were friends. It is my teacher who teaches me, guides me, and makes me understand certain principles of life after tricking me. No one is my enemy. You need to be very open-minded and broad-minded to do this.
Usually people who say this kind of thing either live at the bottom of society or stand at the top of the pyramid. It's almost like the saying that ordinary people are precious. Some people do nothing but comfort themselves that they are ordinary and valuable. Some people have experienced the most magnificent scenery and all kinds of life in the world, and only after they understand the true meaning of life do they realize the value of the ordinary.
This sentence was said by Sima Yi.
Extended information
Sima Yi was smart and sagacious since he was a child, erudite and well-versed in Confucianism. Because the Han Dynasty was controlled by the Cao family, Sima Yi once refused the official position granted by Cao Cao. However, in the 13th year of Jian'an (208 years), after Cao Cao became prime minister, he forcibly appointed Sima Yi as a literary official. Because Sima Yi once supported Cao Cao in proclaiming himself emperor, he gradually won Cao Cao's trust.
Cao Cao granted the title of Queen of Wei and made Sima Yi the crown prince's bastard son to assist Cao Pi and help Cao Pi win the battle for the throne. When Cao Pi was dying, he ordered Sima Yi, Cao Zhen and others to serve as auxiliary ministers to assist Wei Ming Emperor Cao Rui. During the reign of Emperor Ming, Sima Yi was repeatedly promoted to important positions such as general, general, and lieutenant in the Fu army. When Emperor Ming died, he entrusted the young emperor Cao Fang to Sima Yi and Cao Shuang.
After Cao Fang succeeded to the throne, Sima Yi was ostracized by Cao Shuang and promoted to a Tai Tu with no real power. In the tenth year of Zhengshi (249), Sima Yi took advantage of Cao Shuang and Cao Fang to leave Luoyang to Gaopingling to worship the mausoleum, staged a coup and took control of Luoyang, the capital.
Since then, the military power of Cao Wei fell into the hands of the Sima family, which was known as the Gaopingling Incident in history. Sima Yi was good at strategizing and was successful in many expeditions. He once led his army to capture and kill Meng Da. He twice led his army to successfully resist Zhuge Liang's Northern Expedition and led an expedition to pacify Liaodong. It has made important contributions to the development of agricultural economy such as farming and water conservancy.
