Every emperor in history will have his own advisers to help them rise from the struggle for the throne of the crown prince, and these advisers will have two ends, the new king ascends the throne, afraid that his prestige is not as good as that of the courtiers, kill them, or regard them as the founding heroes, and be knighted.

Among all the emperors, Emperor Taizong of the Tang Dynasty did the most popular work, and his kindness and benevolence were recognized by everyone. When he was rewarded for his meritorious deeds, he rewarded the twenty-four meritorious men who accompanied him to lay the foundation of the country, but there was such a person, even if he surrendered to Li Shimin, who was very talented, but he was executed by him without any room, he was Shan Xiongxin.
Shan Xiongxin was a very famous general in the late Sui and early Tang dynasties, extremely good at horsemanship, and fought very well at once, almost invincible. After the Uprising of the Wagang Army, Shan Xiongxin and Xu Shixun, who were originally from a county, defected to Zhai Rang together and made Li Mi the commander, but Li Mi was easily overwhelmed and was soon eliminated by Wang Shichong.
In many battles, Wang Shichong found that Shan Xiongxin was very brave and very clever, regardless of the previous suspicions, he intended to recruit security, everyone was not a calculating person, and they were all heroes and heroes, Shan Xiongxin went to Wang Shichong. However, Xu Shixun weighed it up and chose Li Tang, and he also strongly advised Shan Xiongxin to go with him, but unfortunately, Shan Xiongxin's professionalism was really too heavy, so he chose Wang Shichong, who would weigh himself and was in the upper hand at the time.
Shan Xiongxin was indeed very highly regarded after joining Wang Shichong's troops, and Wang Shichong appointed him as a general, giving him considerable power and status. Faced with such a situation, Shan Xiongxin was very moved, and he was even more devoted to Wang Shichong's life, killing four parties on the battlefield, bringing serious obstacles to Li Tang's army.
Almost no one knew about this single general, and even once Li Shimin was almost killed by him under the horse, fortunately Xu Shixun arrived in time, which saved his life, which made Li Shimin a headache. Everyone familiar with history should know that in this melee, the Li family won, which led to the later Tang Dynasty. At this time, Shan Xiongxin also conformed to the general trend and led his subordinates to find his friend Xu Shixun and surrendered to Li Tang.
He thought he could show his talents again, but who knew that Li Shimin ordered all the soldiers of the Shan family to die. This can be anxious xu Shixun, many times intercede has no effect, and finally Shan Xiongxin can only admit his fate, before dying to eat a piece of meat sent by Xu, so that a generation of heroes ended.
It sounds like our Taizong is very inhumane, but this is also forced, in such a chaotic world, he can only do this, in order to have no trouble, the history books recorded that the benevolent Taizong is also true, he killed Shan Xiongxin loyal but treated his family kindly, just said, there is no complete good man. But there is a more interesting thing, the Huangchao Uprising that accelerated Li Tang's demise was actually a descendant of Shan Xiongxin.
