Take one habit you have noticed about China — hot water, shoes off at the door, a gift that has to be pushed back twice — and this site will tell you what put it there, and when.

How a piece is built

Three moves, in order. First the habit itself, described the way you would actually meet it. Then the history: the campaign, the product, or the price that made it normal. Then where that leaves you — what changes in practice, and what does not.

The middle section is the point of the site. A habit with no traceable origin does not get a piece.
