Xi Yun was a famous Confucian student of the Eastern Han Dynasty, who was born with a straight nature and liked to say something. When he was 12 years old, his mother died, and his grief during filial piety exceeded the rules of etiquette. When he grew up, he went to study the Han Poems and the Yan's Spring and Autumn, and became proficient in astronomical almanacs.
During Wang Mang's reign, Yu Yun came to Chang'an, wrote to Wang Mang, and even persuaded him to abdicate and return to the Han Dynasty. Wang Mang was furious after reading the recital and immediately ordered his arrest. However, when Wang Mang wanted to convict Xi Yun, he found that he could not do it. It turned out that Yu Yun's suggestion was deduced from the scriptures and other proverbs that were highly respected at that time, and Wang Mang had also usurped the throne by means of proverbs, so there was no way to deny Zhi Yun's words.
Therefore, Wang Mang asked his henchmen to go to Zhi Yun and ask him to admit that he was mad and talking nonsense. After hearing this, Yun Yun burst out and scolded, "Everything I said is based on the celestial signs, and this is not something that a madman can make up!" At this point, Wang Mang was completely out of control, and could only put him in prison, thinking of finding an opportunity to kill him later.
Later, Wang Mang pardoned the world, and Zhi Yun escaped with his good friend when he came out of prison. By the time Wang Mang remembered, it was too late, and he could no longer find where Zhi Yun had gone.
Later, emperor Guangwu rose, and After several twists and turns, he became an official in charge of the eastern gate of Luoyang. Don't look at his low official position, but he attaches great importance to his duties, even if the magnates enter and exit the city gate, they cannot violate the rules of the city gate. The most outrageous thing is that even the Guangwu Emperor Liu Xiu's entry and exit at the city gate was managed to death by Zhi Yun.
Once, Emperor Guangwu took a group of people to the outskirts of Luoyang to hunt for a day, and when he returned to the city, it was already late at night. When Emperor Guangwu's car reached the Upper East Gate, the city gate was already closed. Because this was the gate of the city guarded by Zhi Yun, Emperor Guangwu's entourage came and asked Zhi Yun to open the door, but he refused.
After a while, the Guangwu Emperor Liu Xiu personally led ma li to the bridge and ordered Zhi Yun to open the door. Unexpectedly, Yu Yun said: "I can't see clearly at night, no matter who wants to enter the city, or according to the rules of the imperial court, you can't open the door casually." Emperor Guangwu had no choice but to take a detour to the East Central Gate and enter the city.
The next day, Emperor Guangwu was trying to ask Qiu Yun for questioning, but the recital that did not want To Begyu was sent in advance. The song says: "Your Majesty went hunting in the distant mountains and forests, and the day was not enough, and did not return until late at night." If this continues, what will happen to the major national affairs?" Emperor Guangwu looked at the song, and the qi in his stomach was gone, and he said in a loud voice, "This stubborn old man really has the guts and insight!" Therefore, he ordered someone to reward Yu Yun with a hundred pieces of cloth and demoted the official who was in charge of the East Middle Gate.
When Wang Mang was in power, Yu Yun was because Wang Mang did not get his handle, and accidentally let him run away during the amnesty. The second time Emperor Guangwu was here, it was because the emperor was a Ming Emperor who could listen to advice, and Only then was He Yun safe and sound. It is not simple for a person like Yun Yun, who has a straight personality and dares to act boldly, to survive after disobeying the emperor.
