The architectural gem now serves 80 patients per day, with a fifth of places reserved for HK residents on Comprehensive Social Security Assistance. For paying customers, however, consultations for internal diseases start at HK$150, herbal medicine costs HK$55, and acupuncture therapy sets you back HK$300. If you’re one of those people who’s terrified of real hospitals and real doctors (that’s going to be an issue when you’re in your 80s) this is the place for you.

In 2000 the Antiquities Advisory Board ruled that the 600 square metre space qualified as a Grade I historic building and the Lui family, who still owned it, donated the building to the Government in the same year. Aside from practising TCM, they've also turned the best part of it into a free museum which is a great way to learn more about the craft. Only trouble is you'll have to battle Mongkok’s natural defense system, the wall of smelly tofu, to get there.

That wart’s not going to get rid of itself.
