+# Simplified Chinese (`zh-CN`)
+
+Catalog: `src/i18n/locales/zh-CN.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+The catalog started from the Chinese locale by abiyeenzo (#914) and the
+Simplified Chinese localization by EDIT-Aeterna (#979); the rest was translated
+for the current English and reviewed against both.
+
+## Style
+
+- Mainland usage and Simplified characters. Address the user neutrally, without 您/你 where a plain imperative works: 「点击地图」, 「重试」.
+- Chinese has no case: an UPPERCASE English HUD label becomes the same short Chinese label. Keep labels as short as the English: 「实时」, 「过期」, 「关」.
+- Full-width punctuation in Chinese text: ，。：；？！（）“”. A dash is 「——」 without spaces; keep `·` as the HUD separator and `…` for ellipsis.
+- One space between Chinese and Latin letters or digits: 「AIS 船舶」, 「24 小时」, 「{count} 个」. No space next to full-width punctuation.
+- Units: km, m, km/h, m/s, kn, ft, MW, °, % stay as written; time words are 小时, 分钟, 秒 after a number (「5 分钟前」).
+- Product names, provider names and codes stay as they are: Google, Cesium, CelesTrak, NOAA, FIRMS, AIS, ADS-B, GNSS, CCTV, HUD, CRT, NVG, FLIR, WHOT/BHOT, Ironbow, CONUS.
+
+## Plurals
+
+`Intl.PluralRules('zh-CN')` has one category, `other`: a `tn()` entry has only that form. Use a measure word next to the number where Chinese needs one: 「{count} 个密钥」, 「{count} 架飞机」, 「{count} 艘船」.
