The emperor even dared to kill his sons, brothers, and fathers, saying that he did not "dare" to move a descendant of the former imperial family, do you believe it?
Not killing a person is not necessarily because you "don't dare", but also because you don't have to. Chai Jin is a person who makes it "unnecessary" to kill him.
Chai Jin likes to dance with guns and sticks, but there is no description of his real use of force in "Water Margin" (the "three generals in a row" when doing Fang La's horse is obviously a fraudulent defeat of the Song army), and he is certainly not a unique master like "Lü Bu among people";
He has the reputation of "a good man who specializes in taking the world to come and go", but he has no ability to know people, and he can't see a good man like Wu Song who is not famous (before fighting the tiger) but has real ability, but he treats the incompetent and arrogant so-called Hongjiao head with kindness;
His greatest trust was the "Descendants of Emperor Shizong of The Great Zhou Dynasty", and there were "Iron Coupons for The Oath of Oath from Emperor Taizu Wude", but Yin Tianxi, a little brother-in-law of the prefect, dared to rob his family's garden water pavilion and dare to sweep his uncle out of the house! The gold content of this "descendant of the Great Zhou Dynasty" has also been greatly devalued with the passage of time, and has been reduced to the point of being worthless.
Chai Jin has funded Many good men such as Lin Chong, Song Jiang, and Wu Song. But when he reached Liangshan, he did not enter the leadership. Because his ability to win people's hearts was not good at all, he did not have a high prestige on Liangshan.
Chai Jin's greatest credit is probably to go undercover at Fang La and become a donkey. This kind of "infernal path" created convenient conditions for Song Jiang to break Fang La, but it brought trouble to Chai Jin: "I also worked as a donkey at Fang La's place, and if the traitors knew it in the future, they slandered yu before the Son of Heaven, saw the responsibility, and chased after the commandment, wouldn't it be insulted?" So Na returned the commandment and returned to his hometown to serve the people.
Chai Jin's own literary strategy and talent and prestige were not the best choices; after leaving the Liangshan clique, he did not become an official, and he did not have military power in his hands. Such a chai jin did not pose a threat to the court of the Great Song Dynasty at all.
Song Jiang also did not have a martial strategy, but he had the cohesion necessary to be a leader. He was able to bring together more than a hundred good men of all kinds and personalities, posing a great threat to the Great Song. This skill is carried with you and will not be extinguished due to the level of official position. Therefore, the Song River after zhao'an still has potential threat power and is the object that the Great Song court must eradicate.
And Chai Jin, who could not pose a threat, what need did the imperial court need to kill him?
