The Chronicle of History once wrote: "The vassals of the auxiliary humerus are worthy, faithful to the way, in order to serve the Lord." "A courtier who devotes himself wholeheartedly to the end and carries out his loyalty to the end is a dream for the monarchs of any dynasty in ancient times. Ming Jun could not govern the whole world on his own, and even the best emperor needed his own exclusive help.
In the history of the Tang Dynasty, Tang Taizong Li Shimin can be described as a wise and wise prince who is extremely good at employing people. Since 615, he has been running on the battlefield of the anti-Sui, accumulating a great deal of strength in the process of the uprising. He was a gracious corporal and benevolent, which made all those who came to him willing.
In the struggle for the founding of the Tang Dynasty, li Shimin's wise men will be the most. Cheng Yaojin is one of them, he was born in 589, he is strong and brave. In 610 he organized an armed force to protect his neighbors in his hometown of Jeju, which was directly appreciated by Li Mi and joined Li Shimin's command in 619.
Cheng Yaojin himself was a rather arrogant figure, his origin was not too bad, and he was also an official. At the same time, he was also a fierce general who used a horse mallet, and he was very outstanding in both force and leading troops. Such a figure must come into the army with more or less pride, and he is no exception. It was not at all as humble as Qin Qiong, who came with him, but on the contrary, the youthful pride was vividly reflected.
For such a general with an attitude, Li Shimin was naturally very happy to make friends with him. For the arrogance that Cheng Yaojin embodied, this outstanding leader completely conquered this "thorn head" just with his own benevolence. If the master he serves is a wise and noble figure, then what is there to complain about? Therefore, this general was extremely convinced of the King of Qin from then on, and completely implemented the word loyalty.
In 620, Cheng Yaojin showed great power in the Battle of Song Jingang, and then in 621 gave Dou Jiande a major blow. The achievements made on the battlefield not only brought him fame and fortune, but also made the relationship between kings and subjects closer. In 624, in the face of the exclusion of the crown prince, his first thought was the safety of Li Shimin. In the change of Xuanwu Gate in 626, he did not hesitate to closely guard the King of Qin.
Such a loyal minister, who was also one of the most trusted people in Li Shimin's later years, even gave Cheng Yaojin a secret mission just before his death, which directly allowed Datang to continue for another 200 years. In Tang Taizong's later years, Li Chu's affairs were what bothered him the most. The crown prince Li Chengqian's heart was not correct, the fourth son Li Taigong was in calligraphy and painting, and the ninth son Li Zhi was weak in temperament, neither of which one was the best choice.
But after several thoughts, although the ninth son Li Zhi has a soft personality, he has a benevolent heart. In any case, an emperor who takes the people as his essence and sympathizes with the world is definitely better for the people. In this case, Li Shimin asked Cheng Yaojin to secretly protect the weak future crown prince, to prevent those who plotted against him from taking advantage of the opportunity to rebel and directly seize the throne that was not yet stable, so that the Tang Dynasty would completely change the sky.
Therefore, after the death of Emperor Taizong of Tang in 649, Cheng Yaojin personally led a flying cavalry army to escort Li Zhi back to the dynasty. According to the New Book of Tang, he guarded the gates of the temple for three consecutive months, guarding all assassins. After Emperor Gaozong of Tang ascended the throne, he returned to the army and continued to fight for the Tang Dynasty, thanks to the Battle of the Western Turks in 656.
It is also with the completion of Cheng Yaojin's secret mission to Li Shimin that a monarch who loves the people continues the style brought by the rule of Zhenguan, and the Tang Dynasty laid a solid foundation for the great cause of Jiangshan that lasted for 200 years, known in history as the "rule of Yonghui". A good dynasty is naturally indispensable to an outstanding emperor, but his side is indispensable to the unrepentant hard work of the humerus.
