When the Hu attack and massacre the Yan, didn't they also follow the principle of the Yan people.
Those who are not our race, must not have the same hearts.
This is the principle the Yan people used to massacre tribes and clans of the south, north, west and east of their borders
Then after they killed all of these tribes and clans they claim that the land has always been land of Yan and Huang. They would bring up some myths about how the Yellow Emperor and Chiyou fight in this land and this land is the same land.
All of this is just made up story they made to justify it.
and as empire always do, they always think that the sun would never set. And the sun would set eventually and the imperial blowback would be felt by the people
When the Hu people come to the Central Plains, they come with vengeance in their hearts.
Since the Yan people did not treat them as people, then why should they treat the Yan people as people?
