Chinese Input Methods
Here's a introduction to Chinese input methods.
The labels are 2 different input methods for Chinese, used in mostly Taiwan.
The labels on the upper right is “bopomofo”. Look at left column, keys 1 Q A Z, we have ㄅ ㄆ ㄇ ㄈ.
The lower right is Chinese input method called Cangjie (倉頡).
Chinese has thousands of characters. You need to know 2 to 3 thousands of them to read newspaper.
Chinese Input Methods
To type Chinese, you need to use what's called “input method”.
There are more than ten input methods for Chinese, invented at different times by different people in China and Taiwan.
Chinese input methods can be roughly devided into 2 categories.
- Sound based. You need to know how a character is pronounced, before you can type it.
- Shape based (based on character/stroke). You need to know how a character is written, before you can type it.
Sound based methods are far more popular, used by most Chinese, because it's a system anyone who speak standard Chinese can learn in a day.
Character shape based methods require learning, and is in general faster and more accurate. Because, for each character, there are usually over ten homonyms (character of the same sound), so sound based system popup a selection to let you pick the right character. But character based input don't have this problem.
(but as time goes by, sound based might actually be faster due to guessing at whole phrases with Artificial Intelligence tech, for inputting the type of text that's everyday speech. For poetry, academic writing, or any text that's not commonly used daily by average people, character based is much better.)
Sound Based System: Pinyin and Zhuyin
The most popular input methods are:
- pinyin (拼音)
- zhuyin (注音) (aka bopomofo)
Both are sound based.
Pinyin input method is mostly used in China. Pinyin is a phonetic system using English alphabets. Any USA keyboard can type pinyin. No special label is necessary on the keys.
Zhuyin (aka bopomofo) input method is mostly used in Taiwan. Zhuyin is a phonetic system special symbols. It is almost the same as pinyin, except that it uses special symbols instead of English alphabets. Any USA keyboard can also type zhuyin, but if the keys don't have zhuyin labels, you'll have to know which keys are what zhuyin characters.
For example, to type the character我
(meaning “I, me”, pronounced “wo”)
in pinyin, you press w o.
in zhuyin, you press j for ㄨ and press i for ㄛ.
Character Based System: Wubi and Cangjie
in China, the second most popular Chinese input method is Wubi. Its a shape based system.
In Taiwan, the second most popular Chinese input method is Cangjie. Its a shape based system.
Both of these require labels on the keys to learn it.
But in China, there's no keyboard with wubi labels, because most people using this method just memorized it. (keyboards in China are just USA keyboards without any special label on the keys.)
In Taiwan, most keyboards have dual labeling, of Zhuyin and Cangjie. Actually, most keyboards have another label for the Dayi system. So, a key usually has 4 labels: English, Zhuyin, Cangjie, Dayi.

Note: pinyin input method has lots variations, that use shortcuts and artificial intelligence to guess, to increase efficiency.
