The army of the Han Dynasty could defeat the Huns, but the Huns swept Europe. So how powerful were the Han Dynasty, the Huns and Rome?

I'll tell you what, can you say that history should be practical? Xiongnu? Joke! It just swept the barbarians in Europe at that time, such as Goth and Alan Xiongnu, which did not pose a threat to western Rome at all. East Rome was at war with Sassanian Dynasty and had no energy to deal with Xiongnu at that time, so it used money to make peace, that is, Attila, the leader of Xiongnu at its most powerful time, did not pose a threat to Rome. Although Rome had declined at that time, a powerful army was still alive. Xiongnu's army did not flood the territory of Rome. Even though they occupied Hungary, the Germans finally dared to go back. The Huns first appeared in Europe in 376 AD, that is, more than 2 years after being driven out by the Han Dynasty. At that time, the weapons technology of the Huns could not catch up with Rome, but the fighters were not prepared for the attack. It was said that the Huns only conquered some barbarians in Europe, so it was powerful.

At that time, the Western Han Dynasty, which drove out the Huns, was stronger than Rome after 376 AD, and the Huns were always.
