Six posts, one from each section. Each is the site's method applied to a question readers actually arrive with — not the newest, and not the longest.

The rule behind all six
If a number appears here, it came out of a script or a dataset that can be re-run. Where that was not possible, the post says so in its own last section rather than rounding the gap away.
Six sections, no main line: everyday China, health, supply chains, open data, 海外华人, and the AI tooling I test for a living. The full list is on Browse; the shorter pieces are on Notes.
The newsletter carries the new posts every two weeks, with the numbers and the links to check them.
