Enjoy,
Qingqiu - This is the same clan that Miao Miao was part of. Since it's the name of a clan, I've translated it as it sounds, but it can also mean green hills.
Di - This name has been popped up quite a few times now, e.g. Di barbarians. I don't think It's one single clan/country. In real ancient history, Di was used as a generic name for the northern ethnic minorities during 221BC-220AD. If the story is aligning to history, you can think of them more as a bunch of tribes that might ally together.
