The numbering system can also vary by region within a country. Northern
and central Vietnam uses a zero-based system while southern Vietnam uses
a one-based system, and somehow both are national standards. [1] I'm
unsure if there's a well-defined boundary between the two systems, but
if there is, I like to think someone has built a building straddling the
two, just to mess with us.
