I think this cheap (though fairly well photographed) porn had some sort of plot, but the lack of subs made it hard to follow. Also, the print I saw was savagely cut, which means there must be a hard-core version around somewhere. There are young women cat-fighting in front of the emperor, a couple of young virgins experimenting with a long phallic object, and a very long (apparently all-night) sex session, which is quite well done.
Reviewer Score: 5
I later worked out that former b-grade actor Wai Wang played the emperor, which means his career must have gone downhill somewhat since the Shaw Bros glory days.
Overall, not a bad time-waster.
