Who is the historical figure mentioned in "Have a plan to deal with and predict events with wisdom"?

? Xu Yun, courtesy name Shizong, was born in Gaoyang (now Gaoyang County, Hebei Province). During the Three Kingdoms period, he was a minister and famous scholar of Cao and Wei, and he was an official leading the army. Befriend Li Feng and Xia Houxuan. Because Li Feng and others planned to kill Sima Division and suggested that Cao Fang seize Sima Zhao's troops to attack Sima Division, he was exiled to Lelang by Sima Division and died on the way.

As the old saying goes, "Judge a person by his appearance, and you will lose his talent." Because Ziyu was thick, short, ugly, and clumsy in tongue, Confucius felt that he was not suitable for study and politely refused to accept him as his disciple. After Ziyu was rejected by Confucius, he went home and studied hard to cultivate his virtue. A few years later, he traveled to the south to give lectures, and more than 300 people studied with him. Ziyu's reputation spread throughout the vassal states at that time, which could be said to be a slap in the face of Confucius. ? Xu Yun almost lost his good wife because he judged people by their appearance. As for this Ruan, she is not only quick-thinking and eloquent, but also extremely insightful. She always sees things accurately and is very strategic. ?

When Xu Yun was appointed as the Minister of Civil Affairs, most of the officials he selected were his fellow villagers. Therefore, Emperor Wei Ming Cao Rui sent Huben guards to arrest him. When Xu Yun was escorted out of the gate, the Ruan family chased him out and warned him: "A wise monarch can only persuade him with reason, and never pretend to be pitiful and ask for forgiveness." After Xu Yun was escorted to the main hall, Emperor Wei Ming questioned him, Xu Yun used the method taught by his wife to persuade people with reason, and replied in a neither humble nor arrogant manner: "Confucius said that you should recommend people you know well. My fellow countrymen are people I know well. Your Majesty can inspect them to see if they are qualified for the job." /p>

If you are incompetent, I will voluntarily plead guilty and be punished." After the inspection, Emperor Wei Ming confirmed that the people appointed were suitable and released Xu Yun without saying a word. Seeing that Xu Yun's clothes were ruined, he issued an edict to give Xu Yun new clothes. ? When Xu Yungang was arrested, the whole family was frightened and cried non-stop. Only Ruan remained calm and kept comforting everyone: "Don't worry, my husband will be back soon." She even cooked the food herself. I cooked millet porridge and waited for Xu Yun to come home for dinner.
