I think I made my point very clear:
*Old districts —> Yes, keep them as boundary=historic. And yes when I improve the boundaries, will also improve the old district boundaries.
*Old communes —> No, too many of them, most of which are not well-known.

Anyway, I will be drawing from the southern provinces northwards. It will probably take more than 2 years so I won’t be touching your beloved Quảng Ninh communes until then.
