Yeah, it's ... "Dixing got rendered uninhabitable, but go there anyway!" combined with 10k years of no-one updating the fucking treaty?! Zhao Yunlan, please do your bureaucratic thing!

I admit I have zero interest in any "man pines for woman" plotline ever, so I was already uninterested, but seriously. Though now I'm wondering about Zhang Shi's role in all this - orphan Ma Gui took in before discovering he was from Dixing? IIRC Zhang Shi was a bit after Shen Wei's time.
