how to use Fcitx under MDK9.2 english environment?

I have searched the forum and got various explanations:

1. change i18n

2. change .bashrc and add the following line:

#FCITX
export XMODIFIERS="@im=fcitx"
export XIM=fcitx
export XIM_PROGRAM=fcitx
#LOCALE setup
export LC_ALL=zh_CN
export LANG=zh_CN
#load fcitx
fcitx&

by the way, is it zh_CN or zh_CN.gbk (or gb2312) which one?

3. change xinitrc
however, none of the above method seemed to have worked.

My locale output is like this and I didn't install simsun font:

LANG=en_US
LC_CTYPE=en_US
LC_NUMERIC=en_US
LC_TIME=en_US
LC_COLLATE=en_US
LC_MONETARY=en_US
LC_MESSAGES=en_US
LC_PAPER=en_US
LC_NAME=en_US
LC_ADDRESS=en_US
LC_TELEPHONE=en_US
LC_MEASUREMENT=en_US
LC_IDENTIFICATION=en_US
LC_ALL=

Thank you in advance.
