[MiKTeX] Chinese fonts for CJK package

[Liming Y. <Liming.Ye@UGent.be>]

Dear All,
This is concerning the available Chinese fonts for the CJK package. Yes, =
indeed, the font Song is readily packaged in CJK, as in the following =
piece of tex file:
    \begin{CJK*}{GB}{song}
    The following is a test line with Chinese texts.\\
    =D5=E2=CA=C7=D2=BB=B8=F6=B2=E2=CA=D4=D0=D0=A1=A3
    \end{CJK*}
And this compiles well. But if I want to use other font such as =
"\begin{CJK*}{GB}{fs}", then the compiler complains with an error =
message of "undefined control sequence". So, my questions are:
1) are there other fonts includes except "song" with the CJK package?
2) where can I find more fonts such as "hei", "fs", "kai" and how to =
install them?
Thank you very much!
