Adding Chinese handwriting on HTC Desire

After using custom rom on my HTC Desire, I found one thing that is seriously missing: Traditional Chinese handwriting input.  No problem, since some one already figured it out.  Go can go to this site, and for HTC Desire, download the "下載 v4 WVGA SD 卡版本 ( 不需要 root, 需要 sd card ) (SE Arc, Desire, Nexus One, Galaxy )" one, which is "HTC_CIME_WVGA_mod_v4.zip".  You need to expand this zip, and you will find an .apk file and a .zip file (zifiles.zip).  The content of the zifiles.zip file (.ziz8d folder) needs to be at the root of your microSD card.  Then you just run the .apk file to install the package.  In fact, you can even move the installation to the microSD card.  Very nice.
