Why this exists
Search for anything Cantonese and you get a language school. Tones, drills, characters, six weeks to fluency. The culture is treated as scenery you pass on the way to the grammar.
But the interesting thing about Cantonese isn't that it's hard to learn. It's what it notices. A culture that sorts every food by what it does to your body — is a diagnosis, not a temperature. That paid HK$18.1 million for the plate and will not touch at any price. That renamed its own almanac from to . That has a verb for idling with no purpose and no guilt — — and still hasn't got round to giving it a written character.
None of that requires you to speak the language. All of it is invisible if you only ever study the language.
Who it's for
Two people, and the same pages serve both. Someone with no Cantonese connection at all who finds this genuinely interesting — which is where I started. And someone with Cantonese heritage for whom it's a second culture rather than a first: the grandchild who recognises the soup but was never told what it was for, and who searches and finds only lessons.
The awkward part, said plainly
I'm outside this culture. That is a real limitation and I'm upfront about it. But it's also the method: outsiders notice what insiders stopped seeing.
Where I get it wrong, it gets fixed in public on the corrections page, with the date.
How that plays out in practice — what gets published, what waits for someone with a better ear — is set out in the method.

The classical systems this culture inherited are documented at hanzi.design, and the wider work on marks and meaning at symbolic.institute.
