Adding Chinese Language to w580i

So, it's been a really long time since I last flashed my phone with anything. However, with my increasing repertoire of chinese songs, it seems quite necessary for me to flash chinese traditional and simplified onto my phone. Unfortunately... I don't remember how to do anything. My phone is a w580, with the following:
EROM Color: Red
Phone ID: W580
Region: AMERICA_1
CDA: CDA102568/15 R8A
Firmware Version: R8BA024
EROM: R3A022

W580_R8BA024_FS_CHINA_RED52
HB1-06_Gen_CDA102568_104_R8A_GENERIC_HONG_KONG
W580_R8BA024_MAIN_CHINA_LA_RED52

And would that be all i need? Is it ok for me to flash a china main onto the phone, even though my region is america? Could someone please explain in a simple manner how I would go about adding the chinese simplified and traditional onto my phone? Thanks a whole bunch in advance guys

you need flash main file(W580_R8BA024_MAIN_CHINA_LA_RED52) ,fs file(W580_R8BA024_FS_CHINA_RED52) first,then flash custom file(HB1-06_Gen_CDA102568_104_R8A_GENERIC_HONG_KONG) if you use far. this firmware can support english, chinese simplified and traditional
