Cheng Biting Jin is also known as Cheng Zhijie, he is a famous general of the Founding of the Tang Dynasty, but also Li Shimin's right and left arm, but also the legendary fierce general who can attack a city with only three axes, since ancient times, the courtiers who are too popular have no good end, why is Cheng Biting Jin quite trusted by Li Shimin, and even Li Shimin is entrusted with heavy responsibilities before his death? What exactly can make Datang continue for 200 years?
We all know that Li Shimin successfully ascended to the throne by virtue of the "xuanwumen change", and the reason why Li Shimin was able to usurp the throne successfully depended not only on judging the hour and sizing up the situation, the key to victory was that Li Shimin had an elite army in his hands. If there were no army behind him to open the way for him, how could Li Shimin shake the guards inside and outside the palace? It just so happened that Li Yuan, as the emperor, did not have a decent guard around and did not have the slightest sense of thinking of danger in peace, which allowed Li Shimin to succeed.
And Li Shimin called the empress, naturally know the importance of the guard, just have the guard is not enough, the palace guard must be their own trust, so that they can save themselves at a critical moment, Li Shimin also clearly knows that he can sit in this position, Xuanwumen's mutiny plays a vital role, so he will definitely not relax the control of Xuanwumen, not only to hold the power of the Xuanwumen Janissaries, but also deliberately set up a flying cavalry battalion in Xuanwumen, this flying cavalry battalion can be one level higher than the rank of the Janissaries. The soldiers in the battalion were carefully selected and selected through layers of selection to enter this battalion, and Li Shimin then selected a hundred warriors from the flying camp, and these hundred warriors were specially designed to protect Li Shimin's safety, and Li Shimin's side could be said to be flies that could not get close to him.
Li Shimin had bribed three Janissary generals from Xuanwu Gate that year, so that Li Yuan had no one to use in the end, and watched Li Shimin control the entire palace. Then Li Shimin will certainly not let this happen to himself, for the sake of safety, the generals of the Flying Horse Battalion are in charge of their respective battalion headquarters, so that there is no situation where one of the generals is too powerful, and the purpose of mutual restraint has been achieved, the generals of each battalion headquarters only have the power to govern the soldiers of their own battalion headquarters, and finally the power of the Flying Horse Battalion is in the hands of Li Shimin, the establishment of the Flying Horse Battalion is like adding a barrier to xuanwumen, if someone wants to launch a mutiny from Xuanwumen, it will be as difficult as ascending to heaven. Therefore, Li Shimin did not need to worry about the danger in the palace.
Li Shimin had been firmly grasping the command of the Flying Horse Battalion until the twenty-third year of Zhenguan, when Li Shimin handed over the power of the Flying Riding Battalion to Cheng Yaojin, which was equivalent to Li Shimin's safety lock, so why would Li Shimin give such an important command to Cheng Yaojin? Who is Cheng Biting Jin? According to the "Great Tang Dynasty Horse Riding Great General Yizhou Dadu Governor Shangzhu Guo Gong Cheng Jun's Epitaph", Zhenguan twenty-three years, just when the weather was hot, Li Shimin gui for the son of heaven of course to find a place to escape the summer, this summer resort location was chosen in Cuiwei Palace, and with him was also the crown prince Li Zhi, at that time Li Shimin's imperial palace was the Taiji Hall, about thirty miles away from the Cuiwei Palace, at that time Li Shimin's body was still quite tough, but after staying in cuiwei Palace for more than a month, Li Shimin's physical state began to take a sharp turn, Sleepless all night, white hair also grew out, to know that the ancient emperors had the corresponding imperial doctors to condition their bodies, Li Shimin did not contract diseases, nor did he eat anything by mistake, so what is the reason? The imperial doctor's medical skills are no more exquisite than his own understanding of his own physical condition, Li Shimin realized that he may be about to reach a great limit, immediately summoned Cheng to bite the gold, and entrusted the flying riding camp to him, before this the flying riding camp has always been personally managed by Li Shimin, never pretended to be the hands of others, Li Shimin can give the flying camp to Cheng Biting Jin before his death, which is how much trust he gave Cheng Biting Jin.
In fact, Cheng Biting Jin did not gain Li Shimin's trust out of thin air, as early as the seventeenth year of Zhenguan, Cheng Biting Jin was guarding Xuanwumen Town, but all the generals of Xuanwu Gate, it must be Li Shimin's 100% trusted people to guard this town, when Li Shimin personally led the expedition, Cheng Biting Jin sat in Xuanwu Gate, not allowing people with rebellious hearts to take advantage of it, Cheng Biting Jin guarded Xuanwu Gate Town for many years, if there were two hearts, I am afraid that it would have been put into action long ago, Li Shimin valued Cheng Biting Jin's ability, and also greatly believed in The character of Cheng Biting Jin. He was the most suitable candidate to take over the Flying Camp, and no one knew the role of the Flying Riding Camp better than Cheng Yaojin.
Li Shimin gave the flying camp to Cheng Yaojin, and also gave him a secret task, Li Shimin was not in good health, then the crown prince Li Zhi was on the throne, in order to prevent people with hearts from launching a rebellion at the time of his death, Li Shimin ordered Cheng Yaojin to escort the crown prince Li Zhi back to Beijing, and must ensure his safety. After Li Shimin's death, the news on this side was blocked, and li Shimin's body was secretly transported to the Liangyi Palace, and on the other side, Cheng Yaojin escorted the crown prince Li Zhi all the way back to Beijing, and when Li Zhi returned to the capital unharmed, Cheng Yaojin completely controlled the situation at the city gate inside the palace, Li Zhi announced the news of Li Shimin's death, and then according to the emperor's will, Cheng Yaojin took over the flying camp, and the funeral of the former emperor was also held as scheduled. Under normal circumstances, the death of the former emperor will definitely set off a huge wave in the dprk, Li Shimin is also a person who has experienced it, if the new emperor ascends the throne without support, the consequences dare not be imagined, and the role of Cheng Biting Jin is to assist Li Zhi to ascend the throne smoothly, and the flying camp is loyal to the new emperor.
As we all know, during the Li Shimin period, he created the "rule of Zhenguan" and laid a solid foundation for the later development of the Tang Dynasty, if Li Zhi did not successfully ascend the throne, would the glory of the Tang Dynasty still exist? Cheng Yaojin successfully completed Li Shimin's entrustment before his death, which to a certain extent paved the way for the two hundred years of the Tang Dynasty.
