Zhuyin Fuhao (注音符號), also known as Bopomofo, is a phonetic system used to represent the pronunciation of Mandarin Chinese. Unlike pinyin, it uses its own symbols rather than Latin letters.

Origins and Current Use

Zhuyin was developed in China in the early 20th century as part of educational reforms to teach Mandarin pronunciation. The first version of the system was created in 1913 and officially published in 1918. Its popular name, “Bopomofo,” comes from its first four symbols: ㄅ, ㄆ, ㄇ, and ㄈ.

In 1958, however, pinyin was officially introduced in China and gradually became the official phonetic transcription system in mainland China. Zhuyin is still used in Taiwan, where it appears in early schooling, dictionaries, children’s books, reading annotations, and keyboard input methods.

What Is Zhuyin Like?

For Standard Mandarin, basic Zhuyin has 37 symbols: 21 initials and 16 finals, also called rimes. These symbols are combined according to the rules of Mandarin syllables, so not every possible combination forms a valid syllable. Tone marks are also added to show the tone. Below, you can see the main correspondences between Zhuyin and pinyin:

Although there is a mark ˉ for the first tone, it is usually omitted in everyday writing. The neutral tone is marked with a dot. In horizontal writing, it is usually placed before the syllable, as in ˙ㄇㄚ.

How Is Zhuyin (Bopomofo) Used?

Zhuyin combines initials, finals, and tone marks to form complete Mandarin syllables, just as pinyin uses Latin letters to represent sounds. For example, the greeting 你好 [nǐ hǎo] is written ㄋㄧˇ ㄏㄠˇ in Zhuyin. Both systems show pronunciation, not meaning. To understand a word, you still need Chinese characters and context.

Zhuyin vs. Pinyin

The difference is not just visual. Pinyin is a romanization system: it writes pronunciation with Latin letters and is the most widely used international standard for learning Mandarin. Zhuyin, by contrast, uses its own phonetic symbols and is closely tied to Taiwan’s education system, where children learn it at the beginning of elementary school to read and pronounce characters. Both are useful. Which one you choose depends on the country, your learning materials, and your language-learning goals. If you plan to spend time in Taiwan, Zhuyin may be more useful. If you plan to visit or live in mainland China, pinyin is generally the more practical choice.

One advantage of Zhuyin is that, because it uses its own symbols, it can reduce pronunciation mistakes. Pinyin, on the other hand, can sometimes lead learners to misread sounds by applying the pronunciation of Latin letters in English or another language that uses the Latin alphabet.

Can I Use Zhuyin in the App?

By default, the app uses tone-marked pinyin. However, you can change the transcription mode in the app settings. The available modes are:

• Tone-marked pinyin: nǐ hǎo
• Pinyin with tone numbers: ni3 hao3
• Pinyin without tones: ni hao
• Zhuyin: ㄋㄧˇ ㄏㄠˇ

Please note that Zhuyin mode is not compatible with the “Choose Tone” and “Write Pinyin” games or with lessons. In those cases, the app will continue to use tone-marked pinyin.
