They're Bopomofo — Taiwan's phonetic system for Mandarin.
If you know Mandarin but have never learned these symbols, start here. In a few minutes, you'll understand how they represent the sounds you already know.
Let's Play →Bopomofo (ㄅㄆㄇㄈ) is a phonetic alphabet used in Taiwan to represent the sounds of Mandarin Chinese. It's not a new language — it's a simple system that helps you read and pronounce Chinese characters.
It's not a new language. It's a new way to write the sounds you already know.
Bopomofo has 37 symbols — 21 initials and 16 finals — plus 5 tones. Only four tones have a written mark; the 1st tone is left unmarked:
e.g. b, p, m, f, d, t, n, l …
e.g. i, u, ü, a, o, e …
1st tone has no mark; then 2nd, 3rd, 4th and neutral — tones aren't counted in the 37
Go step by step, from sounds to real words.
Tap any card to hear it. Pinyin equivalents are shown so you can connect what you already know. 點卡片可聽發音。
The English sound hints are close approximations — let the audio be your guide. Sound is spoken by your device's built-in voice, so a zh-TW (Traditional Chinese) voice gives the truest match.
Thirty cards. The front shows only the Bopomofo — say the sound out loud, then tap to flip. The back gives a real example word that uses the symbol, spelled out in full. 點卡片翻面。
Bopomofo symbols are miniature Han characters, so the same universal stroke principles apply. 筆順原則與漢字相通。
Strokes flow downward: upper parts are written before lower parts.
Left components come before right components.
When strokes cross, the horizontal stroke usually goes first.
Enclosing frames are drawn before their contents; the bottom stroke closes last.
For symmetrical shapes, the middle comes first.
Tiny finishing touches — dots, short ticks — are written at the end.
The 1st tone is unmarked. The 2nd, 3rd and 4th tone marks sit at the upper right of the final — or of the whole syllable block. The neutral-tone dot sits centered above the initial (vertical text) or before it (horizontal text).
ㄧ is written vertically in vertical text and horizontally in horizontal text — it always lies along the direction of writing.
Each syllable block fills an imaginary square, the same mental frame used for Han characters. Keep symbols compact and balanced inside it.
Pick a symbol, then trace over the guide with your finger or mouse. 選一個符號，跟著描。 The picker offers 12 common symbols to practise — the six principles above cover all 37.

Bopomofo annotates the pronunciation of Han characters — 「注音」 itself means 標註漢字的發音, marking the pronunciation of Han characters.
Late-Qing scholars launched the 切音字 movement to give Han characters a phonetic script. 章太炎 created his 紐文/韻文 (1908), borrowing the kana approach — simplifying components from seal-script characters.
In 1913, the ROC Ministry of Education's 讀音統一會 adopted Zhang's system; 1918 brought the official promulgation of 注音字母, renamed 注音符號 in 1930. The 1932 revision settled the 37-symbol form used today.
The mainland used Zhuyin until 1958, when 漢語拼音 replaced it. Taiwan never stopped — every schoolchild learns it, and it remains the standard for dictionaries, children's books, and the island's most-used Chinese input method.
