use simsun font in Windows

[sevenever]

Hi!
I'm a newbie for emacs. After installing emacs on Windows xp sp2, i
define a fontset in my ~/_emacs as guide from Internet:

;; 设置字体
(create-fontset-from-fontset-spec
(concat
"-outline-bitstream vera sans mono-normal-r-normal-normal-16-*-*-*-c-*-
fontset-my,"
"chinese-gb2312:-outline-新宋体-normal-r-normal-normal-16-*-*-*-c-*-
gb2312.*-*"))

what I want is using bitstream vera sans mono for ASCII char, and
simsun for Chinese char.
But got displayed as below when view a file contain "中文"

Later I use font 新宋体 other than fontset just defined, I got this:

So, how could my emacs cannt display Chinese char as expected?

if any help, my ~/_emacs file is gb2312 encoding.

emacs version: GNU Emacs 21.3.1

Thanks!
