Simplified Chinese Technical Documentation Writing Standards
Merges four authoritative standards: Ruan Yifeng's Chinese Technical Documentation Writing Standards (layout and structure), Microsoft's Chinese (Simplified) Localization Style Guide (localized tone and terminology), Microsoft's Writing Style Guide (writing philosophy), and ASD-STE100 Simplified Technical English (controlled writing and safety-critical documentation). Full original texts of the first three are backed up in references/sources/ (Ruan Yifeng's standards and Microsoft Writing Style Guide are git submodules requiring initialization; the MS Chinese guide is provided as a converted draft in the repository). The core ideas of STE are extracted in references/asd-ste100-core.md, and a quick checklist is available in references/quick-check.md.
Three Basic Principles (Microsoft Voice)
Before writing every sentence, remember: Scan first, read later. Readers usually scan for answers, not read word by word.
- Warm and natural – Speak like you're talking to a colleague, not writing an official document. Use everyday language, avoid formal expressions.
- Concise and clear – Use short sentences over long ones; delete any word you can. Short is good.
- Helpful – Stand on the reader's side and tell them what to do next, rather than just piling up facts.
Hard Typographic Rules
These rules are almost uncontroversial; always enforce them when writing Chinese technical content:
Spaces between Chinese and English
- Leave a half-width space between Chinese characters and English words:
本文介绍如何快速启动 Windows 系统. - Between Chinese and Arabic numerals: Either space or no space is acceptable, but the whole document must be consistent (this standard recommends a space).
- Leave a space between a number and its English unit:
16 GB; no space between a number and percent sign or Chinese unit:6.5%,1000 元. - No space between English/numerals and full-width punctuation:
他的电脑是 MacBook Air。(notMacBook Air 。)
Punctuation
- Use full-width punctuation in Chinese sentences (
,。:;?!“”‘’()、《》); use half-width punctuation when the whole sentence is in English. - Colons: Use full-width
:in document body; use half-width:(followed by a space) in software UI strings, e.g.,错误: %1. - Question/exclamation marks: Use full-width
?!in documents; use half-width? !in software UI. - Use the Chinese enumeration comma
、for parallel items, even if the items are in English:Google、Facebook、腾讯, with和before the last item. - For quotations, use full-width double quotes
“”, and when a quote appears within a quote, use full-width single quotes‘’. - Use full-width parentheses
()for supplementary explanations; do not add spaces before or after parentheses. If the content inside is purely English/numerals, half-width()may be used. - When parentheses contain an annotation, the period goes outside the closing parenthesis:
请参照第 1.3 节(见第 26 页)。 - Ellipsis: In document body, use the Chinese ellipsis
⋯⋯(two character widths, six dots; do not use...or。。。); in UI strings, use the English.... - Do not combine ellipsis with
等: either香蕉、苹果、梨⋯⋯or香蕉、苹果、梨等水果. - Avoid exclamation marks; never use them consecutively (
!!is forbidden). - Em dash occupies two Chinese character widths:
————. - Use
~or—for numerical ranges:132 kg~234 kg; when the two numbers have different units, both include their units. - Use half-width hyphens for compound words and numbering:
氧化-还原反应,图 1-1.
Numbers
- Always use half-width numerals, never full-width
100. - Add thousands separator for numbers of 1000 or more:
1,258,000; optional for 4-digit numbers, but consistent throughout the document. - Use symbols or Chinese names for currency:
$1,000or1,000 美元. 增加到means the amount reached;增加了means the increment; forbidden:降低 N 倍/减少 N 倍– use降低/减少百分之几instead.- Use specific measure words instead of always using
个:两位研究人员is better than2个研究人员.
Sentences and Paragraphs
- Keep sentences short: ideally under 20 characters per clause without punctuation; over 40 characters is unacceptable. A long sentence connected by commas should not exceed 100 characters or 3 lines.
- Use simple and compound sentences; avoid long prenominal modifiers (don't pile too many adjectives before a noun).
- Use affirmative sentences instead of negative ones:
请确认装置的电源已关闭(Please confirm the device power is off) instead of请确认没有接通装置的电源(Please confirm the device power is not connected). - Forbid double negatives:
用户必须拥有删除权限,才能删除此文件(The user must have delete permission to delete this file) instead of没有删除权限的用户,不能删除此文件(A user without delete permission cannot delete this file). - Use active voice instead of passive:
假如尚未安装这个软件(If the software has not been installed yet) instead of假如此软件尚未被安装(If the software has not yet been installed by someone). - One paragraph, one topic; place the topic sentence at the start; paragraphs should not exceed 7 lines, ideally within 4 lines; separate paragraphs with a blank line, and do not indent the first line.
- Use
的/地/得correctly: adjective +的+ noun; adverb +地+ verb; verb +得+ complement. - Use
的sparingly: delete it if it doesn't affect meaning; having two or three的in one sentence makes it verbose. - Pronouns (
其/该/此/这) must refer to a unique and clear antecedent; omit pronouns when possible (Microsoft: you don't need to translate every 'your'/'it' as你的/它).
Tone and Word Choice (Microsoft Voice in Chinese)
