The release of an extended version in Taiwan is not uncommon. In the case at issue, the Taiwanese Version is almost 30 min longer. Thanks to the additional footage, this version is easier to understand. Unfortunately, this version isn't uncut either because 3 scenes from the regular version are missing. The Taiwanese Version is letterboxed with English subs. It's been compared with the HK Theatrical Version represented by the German VHS. One more scene is missing in the German VHS-Version due to censorship, but it hasn't been mentioned because it's irrelevant for the comparison between the HK Theatrical Version and the Taiwanese Version.
