Use Chinese input under English enviroment.

First look at this one to set up the locales and scim correctly. In my case most of the time I use English as my default system language. When I want to input Chinese, I use the console to start the program.

In a console do the following:
> export LC_CTYPE=zh_CN;
> export XMODIFIERS=@im=SCIM;
> scim -d
> soffice (I want to start openoffice here)
Then in the openoffice, should be able to activate the Chinese input method.
