Li Shimin, Emperor Taizong of Tang Dynasty, can be said to be a generation of emperors. The rule of Zhenguan initiated by him made people see the great strength and prosperity of the Tang Dynasty. The Tang Dynasty can be said to be one of the strongest, largest and largest dynasties in Chinese history, and it is also the most open and tolerant dynasty in Chinese history, and the founder of all this is Emperor Taizong Li Shimin. Although Li Shimin has a halo of one kind or another, Li Shimin has a very disgraceful reputation in the history books of later generations. The source of this bad reputation is that Li Shimin tampered with history.

What we need to know is that ancient emperors have special history books to record, and this kind of record is called "Gathering Notes". The function of Gathering Notes is to let the later generations fully understand the words and deeds of the emperor and his living habits, let the emperor know that everything he said is recorded anytime and anywhere, and make the emperor responsible for his actions and standardize his words and deeds. Zhu Zhu's notes can never be changed by anyone, but Li Shimin told history after the change of Xuanwu Gate.

Many people may wonder, what did Li Shimin do to history? Personally, I think that Li Shimin's greatest abridgement of his great book is probably some records before the change of Xuanwu Gate. According to the personal notes of some other unofficial history and veteran ministers who fought against Tang Yuan in those years, Tang Yuan was a very brave and decisive monarch in the early Tang Dynasty, but in the history books left by Li Shimin, Tang Yuan was a fatuous and incompetent person, so it can be judged that Li Shimin modified his father's image in history.

But it will obliterate the merits and character of the real Li and Li Yuanji in history, and the faces of the eldest brother and younger brother in the history books we see now are cruel and heartless, lacking in ingenuity. In fact, the appearance of these two people in real history has been deleted by Li Shimin without a trace, and we have no way to prove what kind of people these two people are.
