I fo now that there are other separate companies and its branches. Districts don't matter. The branches of the same company are identified by xxxxxx-yyy numbers where xxxxxxxx is the same for all branches of the same company and the yyy is 001, 002 etc.
I like how bears and bashers keep moving the goalposts. First it was “Vinafilms doesn’t exist”, now it is “Ok, Vinafilms exists but it doesn’t have 4 locations”.
