Japanese locale seems normal
I don't think it's fonts missing, as other application and KDE traditional menu can show Chinese properly.
Perhaps that's because my special configuration: screen rotation.
Previously in fedora-12, it does have refresh problem.
Not quite sure it's relevant, I will investigate more.

My xorg.conf which rotate screen to right.
After a few experiment:
1. It does not seem to be related in xorg.conf
2. If I select a Chinese font in System Setting->Look and Feel -> Appearance -> Font -> General. Yes, it act as expected.
3. I have also tested the font substitution qtconfig-qt4. No, that doesn't work.
Guess it's font substitution's problem, but I am not really sure where to check the "actual" font substitution rules.
it's definitely the font config setting which causes this problem. You can take a look at $HOME/.fonts.conf, this config file contains the rule for font substitution and you also have take a look at /etc/fonts for global setting.
After another wiped out all the .font* and few more experiment,
I find out that if I turn off subpixel support, the problem disappear. When turn the subpixel on, the problem occur.
Thus I change the title, and feel free to assign this problem to rightful owner.
F.Y.I: Fedora 14 KDE does not have this problem, perhaps we can back port its improvement from it?
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
and is Fedora ok?
This problem does not occur on Fedora 14 and later.
I have also tested F19, (kde-l10n-4.10.1-1, kde-l10n-Chinese-Traditional-4.10.1-1
and it went well.
How about for a new user?
New users also have same problem.
After further tested, I found that:
1. Font that trigger the bug "Serif", "Sans Serif", "Monospace"
and size need to be between 8 and 12.
You also need to install cjkuni-uming-fonts to reproduce the problem.
Installing cjkuni-uming-fonts-0.2.20080216.1-51 from f18 does fix the bug. So I think this can be fix in cjkuni-uming-fonts
