Usually Hong Kong version firmware support both traditional and simplified chinese input
so , in this case , you can try
K770_R8BC004_MAIN_HONG_KONG_VI_RED52
K770_R8BC004_FS_HONG_KONG_RED52
and then download the custompack for HK version
K770i_1202-3438_R6A_Customized_Hong_Kong
But sometime HK firmware doesn't support simplified chinese input ,If you want simplified chinese input only, download the China / Singapore version.
