Incidentally, Severus also learned an interesting piece of news, which was that the Han people, like them, had black hair and black eyes, completely different from those glamorously fair-haired and blue-eyed barbarians, so relatively speaking, both sides could accept each other better than the barbarians just from their appearance.
After all, compared to the fair-haired and blue-eyed barbarians, the two sides were quite similar after mingling for a long time, and both were quite tall, so in this respect, it seemed they had a better foundation for negotiations than those other glamorous types.
Of course, for Severus, this was just an added benefit. If both sides were cast from the same mold, at least communication wasn't too difficult; if the ethnic differences were too vast, the enormous differences would be apparent from appearances alone, making negotiations somewhat challenging.
