Short answer
Zhuyin—commonly called Bopomofo after its first four symbols ㄅ ㄆ ㄇ ㄈ—is a phonetic system of 37 symbols plus 4 tone marks used in Taiwan to represent the sounds of Mandarin Chinese, functioning as a reading scaffold in the same way phonics scaffolds English reading. Taiwan's Ministry of Education curriculum (12-Year Basic Education Guidelines, published by the National Academy for Educational Research) introduces Zhuyin at the very start of Grade 1 (around age 6–7), dedicating much of the first semester to mastering all 37 symbols so that children can use phonetic annotations printed beside characters to read independently before full character recognition is established. Many overseas Chinese-heritage schools serving Taiwanese diaspora communities teach the same Zhuyin-plus-traditional-characters approach, giving children a phonetic key to unlock Mandarin pronunciation.

What to look for before choosing
- 37 symbols (21 initials + 16 finals) + 4 tone marks; uses a unique non-Roman script, unlike mainland China's Pinyin system.
- Introduced in Grade 1 first semester in Taiwan under MOE curriculum guidelines; children learn symbol recognition, stroke order, tones, and syllable-blending.
- By end of Grade 1, ruby (small) Zhuyin annotations beside characters let children read independently—similar to training wheels for character literacy.
- Differs from Pinyin (Romanised system used in mainland China): Taiwan retained Zhuyin alongside traditional Chinese characters after 1949.
- Taiwan's MOE provides free official stroke-order animations and practice worksheets for all 37 symbols at stroke-order.learningweb.moe.edu.tw.
