What version of SuSE Linux were you using? openSUSE 10.3?

Peng Wu (CC:) and me have recently added some more hacks to
groff-1.18.1.1 and man-2.4.3 which make it work for Chinese man-pages.

Maybe you would like to test that?

You can get the improved groff package from

    http://software.opensuse.org/download/M17N/

for the distributions SUSE_Factory, SUSE_Linux_10.0, SUSE_Linux_10.1,
and openSUSE_10.2.

I can build an improved "man" rpm for you as well if you tell me which
distribution you are using.
