The economy of Song Dynasty was prosperous, but it was stronger than Song Dynasty.

As for the Han Dynasty, you think too much about the Tang Dynasty. Emperor Wu of the Han Dynasty fought against ethnic minorities in northern Xinjiang and dared not peep into the Central Plains for hundreds of years. Even the struggle of the three countries did not enter the Central Plains. The Tang Dynasty wiped out the whole Turkic with 3000 troops. Although Li Jing made great contributions, he had to admit that the Tang Dynasty was very powerful.

Not to mention the Yuan Dynasty that almost conquered Europe and pushed it over the Danube. If we continue to fight, history may change dramatically, and no one can stop the Mongolian cavalry in the early Yuan Dynasty. As for the later period, I have nothing to say. How strong it is in the early stage, how weak it is in the later stage. Take off the 65438+million-strong army, but Zhang Shicheng can't beat Gaoyou. Although procrastination was the worst in the Yuan Dynasty, it was about to be shot down, but it was called back by treacherous court officials. At this rate, we can still defeat the Roman Empire.

They might still be able to fight in the Song Dynasty, but they certainly couldn't fight in the early Song Dynasty. It would be tragic if they met Jurchen, Khitan and Mongolia. Because, you know, it's hard for them to get in without drawing tribes such as Khitan and Jurchen.
