I'd say that this is a zombie movie masquerading as something else, but the structure is so beat-for-beat identical you could swap out the beautiful women for zombies and it'd be indistinguishable from a 28 Whatevers Later film. There's clearly an element of satire involved and much of the movie is presented in a tongue-in-cheek way, plus the feminization of the men in the movie (both through crossdressing and actual transformations into women) is doubtlessly some kind of commentary on gender relations in current Chinese society. The problem with translating these things across cultures is that outsiders are going to be completely in the dark as to what is being commented on. Without that knowledge, it reads as a generic zombie movie with pretty girls, which is fine for what it is.
