=====City=====
Reminder: 'city_city ' is the cities city info extracted from 'city'; 'city_addr1 ' is the cities city info extracted from 'addrline1'; 'city_addr2 ' is the cities city info extracted from 'addrline2'.
The 'city_city', 'city_addr1 ' and 'city_addr2 ' are consistent.
Examples:
CARROLLTON | CARROLLTON
'city_city', 'city_addr1 ' and 'city_addr2 ' beat feature 'city ' because they are detailed.
For records of which 'addrline1', 'addrline2 ' and 'city ' don't contain city info, just keep feature 'city ' as the 'city_cleaned'.
