What do you mean, "Han Confucian classics, Jin, Tang Wang Ba, Song snot, sloppy"?

The Han Dynasty advocated the study of Confucian classics. But strictly speaking, this phenomenon only happened after Emperor Wu of the Han Dynasty respected Confucianism alone. The "celebrities" in Wei and Jin dynasties advocated talking about something illusory. The more others don't understand, the more brilliant they are. In fact, they are all bad habits of nobles! As a result, the Western Jin Dynasty lost its country for decades, and the Eastern Jin Dynasty gained numerous rights, which was finally taken over by Emperor Wu of Song. The so-called "turtle of the Tang Dynasty" means that there are so many things in the court of the Tang Dynasty that many emperors inexplicably put on green hats. I won't say more details, just look at it. Not to mention snot and slowness in Song Dynasty, both of which describe the characteristics of literati at that time. To add a little more, there is also a confusion of Yuan.
