It means: merge with light, turn into earthly dust, display your talents with the changes of the times, gentle light is as unobtrusive as dust, conform to the times, bend and stretch slowly, gather your scales and hide your wings to wait for time, and pay attention to the changes at any time.
This sentence means that Sima Yi is good at covering up his own sharp edge, pitching with the times, and watching the changes of the wind and cloud while diving.
It comes from The Book of Jin: On Xuandi Ji: "Harmony is the same as dust, and it is comfortable with the times; Squatting and diving, thinking of the wind and cloud. "
The Book of Jin Xuandi Ji is a biography of Sima Yi. The Book of Jin is one of the twenty-four histories of China, co-authored by Tang Fang Xuanling and others. It records the history from Sima Yi's early years in the Three Kingdoms period to Emperor Yuan Xi's second year in the Eastern Jin Dynasty (42), when Emperor Wu abolished the Jin Emperor and became independent in the Song Dynasty.
expanded information
Sima Yi was the founder of Sima family's control of Cao Wei regime.
in Cao Cao's time, Sima yi rarely showed his dew. In Zi Zhi Tong Jian, he recorded two strategies for Cao Cao, one is to look forward to Shu and the other is to evaluate Guan Yu, both of which are brilliant ideas.
The first time was in 215. After Cao Cao captured Hanzhong, Sima Yi suggested that he further capture Chengdu. Cao Cao was anxious to return to his division and didn't go. The second time was in AD 219, when Liu Bei claimed to be the king of Hanzhong and captured Hanzhong. Guan Yu responded in Jingzhou, making a great move, flooding the seven armies, cutting Pound, falling to the forbidden, and subliming China. Some rebellious armed forces near Luoyang responded to Guan Yu's behavior, and Cao Cao wanted to move the capital.
Sima Yi advised Cao Cao to hold his ground. He came up with an idea: Yu Jin surrendered, and Pound was killed, not because of Guan Yu's military power, but because of the heavy rain, not because of military incompetence, so don't rush to move the capital. Moreover, Guan Yu's noise is so great that Sun Quan must be unwilling. He might as well join forces with Sun Quan to encourage him to copy Guan Yu's back road and promise to seal Jiangdong to him in the future. Later, Cao Cao did just that, and Guan Yu was killed.
During the struggle between Cao Zhi and Cao Pi, Sima Yi supported Cao Pi, so it was reused in Cao Pi's period. In Cao Rui period, he was the main commander-in-chief, dealing with Shu Han, pacifying Liaodong and leading troops to fight. Cao Fang, the third emperor of Cao Wei, was only eight years old when he acceded to the throne. He was entrusted as the minister in charge of life and assisted with Cao Shuang. At first, the two men cooperated very well. They each had 3, chosen men, who took turns to stay at the hotel, and * * * held the office of state affairs.
Later, Cao Shuang issued an imperial edict in the name of the son of heaven, which pushed Sima Yi out of the power center and promoted him to a teacher in name only. Cao Shuang's cronies held important positions in the DPRK, and several brothers also controlled the imperial army. Cao Shuang monopolized the power and Sima Yi was sidelined. Since 247, Sima Yi has called himself ill and refused to take part in political affairs. Cao Shuang is not without doubt, Cao Shuang once let confidant lunt to visit sima yi's illness.
Li Sheng told Sima Yi that the son of heaven ordered him to be the secretariat of Jingzhou, and now he has come to bid farewell to the teacher. Sima Yi knew what he had come for, and deliberately played the fool. He was wearing clothes, and his clothes were falling off. He was thirsty for porridge. He didn't hold a cup and drank it with his mouth. He fell on his body and spilled it all over his body. He also said that he was dying and hoped that the general would take care of his children more. Lunt this look, people are sick like this, go back to Cao Shuang they say, Cao Shuang they were relieved.
The Cao Shuang brothers often go out to play in Luoyang City together, and Huan Fan reminds him: "If you leave the capital together, once someone closes the city gate and won't let you go back to Luoyang, what should I do?" Cao Shuang said, "Who dares!" As a result, on the sixth day of the first month in 249, Emperor Cao Fang took his Cao Shuang brothers to visit the Imperial Tomb in Gaopingling outside the city. Sima Yi staged a coup in Luoyang, known as the Gao Ping Ling coup in history.
In the name of the Empress Dowager, Sima Yi closed the city gate, took out his weapon, and sent a message to the emperor outside the city, accusing Cao Shuang of betraying his life, ruining the national code, arrogating power to himself from the inside, guarding the supreme, alienating the second palace, hurting the flesh and blood, threatening the world, and demanding that the emperor remove the military power of Cao Shuang and his brothers.
Sima Yi also gave the other party a bait, just handing over the military power, which could save his life and swear by Luoshui, and specially sent Yin Damu, an official trusted by Cao Shuang, to convey this message. Cao Shuang hesitated for a night and decided to surrender, thinking that if he gave up and handed over the relieving, perhaps Sima Yi would spare his life. Wily Huan Fan, known as a think tank, specially ran out of the city to dissuade Cao Shuang from surrendering. He asked Cao Shuang to directly confront Sima Yi in the name of the son of heaven.
However, as Jiang Ji told Sima Yi, although Huan Fan is wise, Cao Shuang will definitely not listen to Huan Fan. The so-called "Xu's love for beans" means that Cao Shuang doesn't want to struggle hard, but he wants to hold on to the existing prosperity. In the end, Cao Shuang gave in easily, and Sima Yi failed to keep his promise not to kill. Cao Shuang and others were killed for treason, and Huan Fan also died. The power of Cao Wei was completely in Sima Yi's hands.
