Probably from Chinese college students.
Wouldn’t surprise me if Richmond is considered “Central Virginia” now that the Yankees have taken us over.
Hmm. Around where I live, we don’t consider Richmond part of a Central Virginia.
But according to the VDH website, Richmond is considered part of its Central planning region, and Charlottesville/albemarle is considered part of its Northern planning region.
So they may very well mean Richmond metro area when they say Central Virginia.
The planning regions of VDH can be found on this map:
