Sean Gilman’s review published on Letterboxd :
Sandra Ng's third film as the prostitute analogue for Hong Kong, but the first in a decade. It starts with a cartoon-y history of prostitution then throws us into the ultra-modern world of the contemporary brothel. Like the other films in the series, it's an episodic story, going from the speedy intro to a funny bit about a Louis Koo impersonator. From there things slow down in a draggy middle section that ups the vulgarity (relaxed censorship laws, apparently) without being particularly funny. The turn from slapstick to poignancy that the first two films handled so well is rather clumsy here, as the film ends with a lengthy story about Nick Cheung as a triad boss imprison in 1996 (right before the Handover, of course) and only recently freed. Cheung and Ng are good enough to pull it off, but this is still the weakest of the series.
