The Tang Dynasty's Greatest Minister

It's really absurd. I'm baffled. Criticizing the protagonist's personality and conduct is fine, but expecting the author to change the novel's genre according to their own preferences is ridiculous. There are countless different kinds of novels in the online literature world. Supporting characters, power struggles, court intrigue, aristocratic families—these are all too common.

Here's a repost of a comment from Zhihu user Qiuju Luoying: Why did Li Shimin dare to rebel against Li Yuan? Yes, you read that right, it was because of the Fubing system (a military system in ancient China). (This article mainly answers the first part of the question; I won't discuss the Ming Dynasty since I'm not particularly familiar with it.)

As latecomers, the powerful families of Guandong (eastern Shaanxi) were at a disadvantage compared to those of Guanxi (western Shaanxi) for most of the Tang Dynasty. The reason why An Lushan and Shi Siming wreaked havoc for so many years was due to the unequal distribution of regional interests.

I'll just wipe out the Li family, change history, and see what happens.

Why didn't the protagonist kill Li Yuan? He had such a good chance, why did he have to become a subject? Wouldn't it have been better to be the emperor?

Professor Yu Gengzhe once said First, the economic foundation changed. The Fubing system, which previously held power in the central government, collapsed due to land annexation. The professional conscription system led to the Jiedushi (military governors) controlling local military and financial power.

Was Li Shimin not worthy of being assisted? He was a great emperor throughout history; I think being his subject would have been quite good.

Li Shimin's brilliance is undeniable, but fundamentally, it was the Guanlong Group that chose the Li family. Yang Guang wasn't incompetent either, but given the immense power of the aristocratic families at the time, he was overconfident, believing he could weaken them with his own strength. Therefore, he chose the easiest method: external wars.

In the eleventh year of Zhenguan (637), the censor Ma Zhou once said: "The Sui dynasty stored up the Luokou treasury, and Li Mi followed suit; the Western Capital treasury was also used by the state, and it is still not exhausted to this day."

The Sui-Tang Grand Canal was built upon the foundation of existing local canals. Without the construction of these local canals, the Sui-Tang Grand Canal would have lacked a basis. During periods of division, local governments constructed several local canals for their capitals, which, objectively speaking, laid the groundwork for the Sui-Tang Grand Canal.
