GB/T 15834 — China\'s Chinese Punctuation Standard
China\'s national standard GB/T 15834-2011 "Use of Punctuation Marks" is the authoritative reference for Chinese punctuation, effective June 2012. It specifies 16 fullwidth punctuation marks: 。 , ? ! ; : "" 「」 () —— ……, etc.
5 most common errors
(1) ASCII comma (,) in Chinese context — should be 「,」. (2) ASCII period (.) — should be 「。」. (3) ASCII ellipsis (...) — should be 「……」 (6 dots = U+2026 × 2). (4) Multiple punctuation runs (!!! or ???) — standard allows only one per sentence. (5) ASCII straight quotes ("") — should be curly "" or Chinese 「」.
"The real reason for fullwidth: Chinese characters are square. Halfwidth (50% width) breaks visual rhythm next to Chinese; fullwidth (100% width) maintains a unified grid."
Regional adoption
SG + MY Chinese education often overlooks the fullwidth/halfwidth distinction — local Chinese publications frequently misuse ASCII punctuation. HK + Taiwan strictly enforce fullwidth — this is basic professional Chinese typography.
Practical tips
(1) Input method switching: Chinese IME defaults to fullwidth, English IME defaults to halfwidth — don\'t mix. (2) Content copy-pasted from English documents must be fixed. (3) WeChat / Weibo / Moments are lenient, but formal documents (resumes, contracts, emails) must comply.
10 facts about Chinese punctuation
Classical Chinese had no punctuation. Modern Chinese punctuation was imported from the West in the 1919 New Culture Movement — directly influenced by the May Fourth Movement.
The 「。」 (period) was imported from Japan in 1919 — the round shape distinct from Western ".". Classical Chinese used no-symbol spacing to mark sentence ends.
Mainland vs HK/TW quote conventions: mainland uses curly "" (Western-style); HK/Taiwan use traditional 「」 and 『』.
The Chinese ellipsis is SIX dots (……) not three. Correct encoding: U+2026 × 2.
"!!!" or "???" chains violate GB/T 15834. The standard permits only one per sentence.
"&" has no Chinese equivalent — should be replaced with 「与」 or 「和」.
《》 book title marks are unique to Chinese — marking books, films, articles. English uses italics or quotes instead.
「、」 (enumeration comma) is unique to Chinese — used for listed single characters/words (e.g. 红、橙、黄、绿). English uses regular commas.
The Chinese em-dash is TWO fullwidth dashes (——), not one. Used for thought breaks / inline notes.
SG + MY Chinese publications often misuse ASCII punctuation — HK/TW/mainland professional typography is strict about it.
Frequently Asked Questions
(1) ASCII halfwidth punctuation (, . ? ! : ; ") in Chinese context; (2) Punctuation chains (!!! ???); (3) ASCII ellipsis (...) replacing Chinese (……); (4) Missing CJK-English spaces (info-level).
No. It only replaces punctuation (halfwidth → fullwidth). Content and sentence structure are completely preserved.
No. All checking and fixing runs in your browser. Your text never leaves your device.
Quotes require human judgment (open vs close) — the tool flags but does not auto-fix them. Manually replace with 「「」」 or 「""」.

Same principle (fullwidth) but local differences. HK/TW prefer traditional 「「」」 and 『』 quotes; mainland uses 「""」.
Not strictly. Daily chats, no one cares. But formal documents (resumes, contracts, emails, reports, publications) must comply.
When imported in 1919, matching the visual length of English's 3 dots — Chinese characters are ~2× English character width, so 6 dots equals 3 ASCII dots visually.
