This is a common problem , but has fortunatly an easy fix. You can change your language from chinese to english with following actions:
-run regedit
-go to “HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Rockstar Games\Grand Theft Auto V”
-double click on Language
-an window opens – change the text into en-US
or you can go to 3dmgame.ini and change tha zh-CHT to en-US.
