Chuan means flowing water, which is the first clue. This is the wellness arm of The Langham, tucked away from the marble grandeur upstairs, and it runs on Chinese medicine rather than a standard treatment list. You start by finding your element. A short consultation, then a bespoke oil blended to whichever of wood, fire, earth, metal or water you turn out to be. The massage follows your element. A pot of matching tea closes it. There is a sleep programme for the truly frayed. And the hotel's pool waits under a ceiling pricked with fibre-optic stars. The starlit swim is the part you will tell people about. Millers Point has never felt so far from the office.
