well, syntax is one thing, the more important is which fontconfig
file, and what prefix number will you use.

In the past, this was done by font package itself in Fedora: if a
font wants to be the default, it simply sets a prefer list in its
own fontconfig file; if multiple maintainers want their fonts
to be the default, they will have to compete the prefix number:
the smaller number wins (unless the later ones use prepend_first).

To avoid this mess, I had proposed a set of cjk specific config
files with clean and centralized settings, you can see the
whole proposal here:

http://bugs.freedesktop.org/show_bug.cgi?id=20911
https://bugzilla.redhat.com/show_bug.cgi?id=499902

but briefly, what you need to do is to update 65-nonlatin, and
add two cjk specific config files: 65-language-zh.conf and
65-language-ja.conf, see

https://bugs.launchpad.net/ubuntu/+source/ttf-wqy-zenhei/+bug/521163/comments/5

unfortunately, Fedora people seemed not to be very keen to this solution,
for some reasons, and the proposal is currently stalled. Despite that,
I got response from Arne, the CJK fontconfig maintainer for Ubuntu
that he is interested to this:

https://bugs.launchpad.net/ubuntu/+source/ttf-wqy-zenhei/+bug/521163/comments/6

so, I still highly suggest you considering this cleaner solution if you
want to wire up the CJK font orders. Of course, you have to
communicate with Jens and Akira more on this matter.

just a side note, use binding=strong is generally not preferred.
use smaller prefix number if you want to overwrite other rules.
