the Han Empire and the Roman Empire

 It's kind of embarrassing because it seems like you're taking the side of Rome, but it's not like Rome. As I left it in the Ripple, I would predict the White Middle Ages if it were not to clash the regular forces of the two countries (except the colonial forces or the subordinate forces) in the field. If either side carries out a large-scale expedition, I would argue that it is the defeat of the expedition. There is an opinion that the solidarity of the Korean Empire is not comparable to that of Rome, but it is hard to say which is superior to the solidarity of the Roman Empire, which is essentially a tribute and an encirclement, or an economic and military alliance. The solidarity of the Han Empire, which you claim, is still in the early stages of Chineseism, so it is a time when the gangsters revolted when the center was confused. On the contrary, I think that Rome was also a direct management of dispatching a governor, and there were a lot of these colonies that were literally uncomfortable without surveillance. If the regular Han army emptied Loyang, the scholars could stand up in a stampede, and if Rome emptied the capital, Rome would be reluctant to do so because of the Germanic children, I don't think that's a problem.  On the contrary, Han can mobilize Western forces and Rome can also mobilize cavalry from Spain and Nubia.   If you omit Central Asia between the two empires, it's quite a disadvantage for Rome...A significant number of allies are going to be lost on the map.^^ But if you somehow force a border, I'll still predict the centrist. The regular army, in its heyday, was a well-trained force by the implementation of the Duncan system, and Roman anti-professional soldiers who adhered to the system of militia unity... ...the Hundred Middle Ages, the Germanic mercenaries, the Five-Hwan mercenaries...Nubian cavalry and Western strength...The key to these allies is how much the other leader uses their cause and their practicality to disrupt them. I don't think either side has the upper hand in the quantity of supplies.In the end, I think it's the capability of the commander. But I think it would be interesting to have a well-trained military force in the Hunan period and a Roman army with a lot of war experience in the early days of the empire rather than in the Han period.
