Tell me about the decline of the Han Dynasty.

Generally speaking, the positioning of the Han Dynasty (including the Western Han Dynasty and the Eastern Han Dynasty) is about 400 years after the death of Emperor Han Ling. The decline of the Han dynasty is inevitable from a historical perspective, that is, the development of everything will inevitably decline one day. From a direct point of view, it is because the first emperor was young and the consorts monopolized the power, which led to fierce struggle in the imperial court, unstable national foundation, and the central government gradually lost control, leading to a scuffle among warlords. The indirect reason is that there are hidden dangers in the concept of governing the country in the Han dynasty, which is "ruling by Huang Lao and ruling by doing nothing". Local governments are fragmented, and the official system has no elimination mechanism. Over time, corruption will breed and the polarization between the rich and the poor will become more and more serious. When the people are poor and the country is in turmoil, warlords (so-called heroes from all walks of life) are just making contributions. As the saying goes, the luck of a great man will eventually run out, and the wall will be pushed down by everyone.
