What we often say about "speaking of the devil" really has something to do with Cao Cao in the Three Kingdoms period?

People often say "Speak of the devil" to describe that people or things are very timely. This allusion is really related to Cao Cao in the history of Guan.

at the end of the eastern Han dynasty, after the struggle between the party and officials and the yellow turban insurrectionary uprising, the Han dynasty was already teetering and could not maintain its domestic rule. Dong Zhuo led his troops into Luoyang, abolished the young emperor and established the Han emperor. After Dong Zhuo was killed by Wang Yun, his Ministry led Li Jue and Guo Si into Chang 'an, killed Wang Yun and many officials, and placed Xian Di under house arrest. Xian Di was once out of danger when Li Jue and Guo Si fought, but after Li Guo joined forces, they continued to pursue Xian Di.

When Xian Di was cornered, someone recommended Cao Cao to Xian Di, saying that he had made contributions in suppressing the Qingzhou Yellow Scarf Army and could rescue the driver. Before Xian Di's messenger was sent, LiGuo's allied forces had been killed. At this critical juncture, Xia Houdun, Cao Cao's general, was ordered by Cao Cao to lead the army to "protect" and defeat Li Guo's allied forces. Therefore, Cao Cao was given an official title, welcomed the Emperor Xian of Han Dynasty to Xudu (now Xuchang, Henan Province), and began to "take the Emperor as a vassal", eventually achieving a hegemony.

Later, people used the phrase "Speak of the devil" to describe the timely arrival of Cao Cao's escort. The 14th time of Romance of the Three Kingdoms, "Cao Mengde moved to a lucky capital", is based on this history.

what was Cao Cao like in the history of knowledge extension?

Luo Guanzhong's novel Romance of the Three Kingdoms is a household name. In this book, Cao Cao is portrayed as an out-and-out traitor. In fact, Cao Cao in history is quite different from Cao Cao in the novel.

Cao Cao, whose name is Meng De, was born in Pei Guoqiao (now Bo County, Anhui Province). He was a famous politician, strategist and writer in the Three Kingdoms period.

his official rank was as prime minister, and he named Wang Wei as the King of Wu. After his son Cao Pi proclaimed himself emperor, he was revered as the Emperor of Wu and was called Wei Wudi in history. According to Shi Ke's records, Cao Cao was clever and ambitious since childhood. At the age of 2, he was promoted to filial piety by virtue of his family power, and he was appointed as the northern commandant of Luoyang, and then moved to Dunqiu.

in the war of suppressing the yellow turban insurrectionary uprising and punishing dong Zhuo, Cao Cao gradually expanded his military strength. In the third year of Chuping (1992), Cao Cao was appointed as a shepherd in Yanzhou, and part of Qingzhou Yellow Scarf Army was organized as "Qingzhou Soldiers".

In the first year of Jian 'an (1996), Cao Cao welcomed Xian Di to Xudu to "hold the emperor to make the princes". After the battle of Guandu defeated Yuan Shao, Cao Cao gradually unified the northern part of China. In the 13th year of Jian 'an, he became prime minister, led the army south, and was defeated by Sun Liu's allied army in Chibi, and then basically formed a situation of tripartite confrontation among the three countries. The history books commented on Cao Cao: "Being wise is the best", "Being a capable minister in managing the world, being a treacherous man in troubled times" and "writing poems in a horizontal way, consolidating the world's heroes". Chen Shou's evaluation of him in the History of the Three Kingdoms can be regarded as the highest among the three monarchs of Wei Shuwu.

Cao Cao has shown outstanding military talents, and has written books such as Sun Tzu's Brief Explanation and The Book of War. Economically, he cultivated land in the north and built water conservancy projects, which solved the problem of lack of rations and was of great help to the recovery of agricultural production. In terms of literature, Cao Cao also made great achievements, including the collection of Wei Wudi, which was also called "Three Caos" with his sons Cao Pi and Cao Zhi, and he was the leader of "Jian 'an Literature".

Cao Cao is a versatile person who is less bound by traditional ethics and price standards. This kind of thought and character is reflected in his literary works, that is, he expresses his feelings frankly. His poems, such as "Journey in the Hao Li" and "Watching the Sea", are magnificent, generous and sad.

Cao Cao has also made considerable achievements in prose, and his representative works include "Let the county know the truth" and so on. Lu Xun called him "the founder of transforming articles", which means that his articles are not bound by stereotypes, and his words are crisp and clear, sweeping away the habit of writing in the Han Dynasty.
