In ancient times, the loyalty of courtiers was undoubtedly highly valued by kings. In the folk, if a military general changes his camp several times, he will often be considered a wall grass, such as the famous Wenhou Lübu, who is called a family slave with three surnames. However, for Li Shimin, he not only took in ministers like Wei Zheng, but also let Cheng Yaojin, the master of the Three Yi, enter the Ling Yan Pavilion. Then, as a warrior of the Three Changes, what virtue and ability did Cheng Yaojin have?
Although in folklore, Cheng Yaojin was just a flat-headed commoner from a grassy background. But in fact, Cheng Yaojin's grandfather and father are rare high-ranking officials, and in this family lineage, Cheng Yaojin will naturally not be the rude yamano villager that everyone imagines, but a brother with an extraordinary birth.
In the folk, Cheng Yaojin is generally regarded as a blessing general who does not have much real talent and practical learning, has no cultural knowledge, and relies purely on the three-plate axe and his own luck. However, in fact, Cheng Yaojin is good at riding horses and can skillfully use horse mallets, so it can be said that martial arts are absolutely justified. Moreover, the historical Cheng Yaojin can be said to be a brave and resourceful warrior.
The first time Cheng Yaojin followed Li Mi and the second time he followed Wang Shichong, they were both reused. Li Mi asked him to command the most courageous eight thousand men, and praised him for saying that these eight thousand people were worth other people's millions of heroes. This can also be seen from the side, Cheng bites Jin's personal ability.
After following Li Shimin, Cheng Yaojin was loyal to him and helped Li Shimin in his southern conquest of the northern war. He helped Li Shimin defeat Dou Jiande, capture Wang Shichong, and eventually help Li Shimin launch the Xuanwumen Rebellion. It can be said that as a major event concerning Li Shimin's life, being able to participate in the change of Xuanwu Gate is Li Shimin's most trusted minister, and Cheng Biting Jin is among them, which can also be seen li Shimin's trust in Cheng Biting Jin.
Moreover, although Wang Shichong and Li Mi are contemporary princes, they are either lacking in strategy or ambitious too powerful. Now there is no way to verify whether Cheng Biting Jin is good or not, but what can be thought of is that for Cheng Biting Jin, these two people are definitely not the Holy Lords that Cheng Biting Jin wants. Therefore, when the more talented Li Shimin appeared, it can be said that Cheng Biting Jin's change of flag and banner is understandable.
Therefore, it is also a change of flag and a change of banner, three changes of its master, but Lü Bu is for his own interests, and even does not hesitate to betray his two uncles who are very good to himself, so he will also be regarded as a family slave with three surnames. However, Cheng Biting Jin is different from him, and it can be said that Cheng Biting Jin's change of flag is a kind of good bird choosing wood to roost.
This behavior of Cheng Biting Jin is not disloyal, but the prudent use of his loyalty. From this point of view, Cheng Biting Jin's three masters can also be regarded as a cause and a matter of course, perhaps this is the main reason why Li Shimin can accept him and regard him as his important minister.
No matter how good the process of biting gold, it must always be appreciated by the emperor to be useful. Li Shimin was a man with a broad mind and was a rare frank emperor in history, which can be seen from where Wei Zheng was. Therefore, Li Shimin's own heart has become an important factor for Cheng Tonjin to be reused.
Cheng Yaojin is a man, can fight a good battle, and has established an amazing meritorious service for himself. It can be said that when Li Shimin met such a courtier, it was difficult to poison him. Therefore, Cheng Biting Jin's three changes of mastership are really for a reason, and he does not lack due loyalty to his own emperor Li Shimin, and in the end he naturally gets his due credit.
