Z310a firmware check please!

Hello guys! I want to flash my z310a's to Chinese. I've found the firmware for it but not sure if it fits my phone. Please check for me! By the way, i'm using XS++V31. Many thanks!!!

Here is my phone's info i got from WotanClient:
FC ID: 89 7E
EROM: RED CID53
OTP: RED CID51
OTP: IMEI 3540400XXXXXXX
GDFS: Z310a
GDFS: CDA102670/330

Firmware i found:

Z310ALVA_Gen_CDA102669_101_R3A_GENERIC_APAC

Z310_R6BC002_MAIN_CHINA_AL_RED52

If so, what else do i need?
If not, what firmware name should i look for?

You need:
Z310_R8BA024_MAIN_CHINA_AL_RED53
Z310_R8BA024_FS_APAC_RED53 and as a customization
ALVA_Gen_CDA102669_101_R3A_GENERIC_APAC
