What's the meaning of 道郡? I encountered this word '道郡' while reading a story set an China's ancient times. I tried Baidu and got some names such as  '怀道郡' and '狄道郡', so I think '道郡' may be an ancient counterpart to the modern word for 'county' (which is just 郡).

Can anyone give me an exact answer?
“道“ &amp; “郡” were administrative division name.

in 秦 dynasty, the country is divided into 36 “郡“, each one is roughly the size of a province nowadays.



in 唐 dynasty, the country is divided into 15 “道“, each one is about the size of a province today.



county is an acceptable translation; however, i prefer “province”, or “state”.
