Editorial Policy
This page explains how our guides are written and checked, so you can decide how much to rely on them.
Who writes the guides
- Guides are written and edited by the Shoujia Shop team. We use AI tools to help research and draft, and every guide is checked against its sources before it's published.
- Each guide shows the date it was last updated.
- Guides are written for US readers in US units. Where a metric figure helps, we convert it and round it.
Where the numbers come from
| Type of information | What we use | How it's shown |
|---|---|---|
| Rules and limits (airline sizes, building code) | The official source: the airline's or code body's own page | Linked, with the date we checked it |
| Measuring methods and rules of thumb | Published guides from retailers, manufacturers, universities and established publications | Linked, with the date we checked it |
| Conversions (pounds to cups, inches to centimeters) | Published reference charts and NIST conversion factors | Linked; our arithmetic is labeled as ours |
| Disagreements between sources | Both sources | Shown side by side, with what the difference means for you |
If we can't find a reliable source for a number, we leave it out rather than estimate it.
What we won't do
- No claims of testing we didn't do. We don't do hands-on product testing, so we don't write "we tried" or "tested by us."
- No scores, rankings or "top picks." Guides help you judge fit; they don't crown winners.
- No fake reviews or testimonials.
- No recommendation because something is for sale. Every guide includes who should skip the product.
Our relationship with Shoujia Mall
- Shoujia Shop and Shoujia Mall are part of the same company.
- Guide text doesn't name, link to or recommend specific listings. When Shoujia Mall has matching items in stock, they appear in a separate, labeled box, and we may benefit if you buy.
- If nothing matching is in stock, the box doesn't appear. The guide stays the same either way.
Keeping guides current
- Time-sensitive guides, like airline size limits, show the date each source was checked.
- When a source changes, we update the guide and the date at the top.
- When a reader reports an error and we confirm it, we correct the page and update the date.
