First, lets look at a keyboard used in Taiwan.

The key labels show 2 different input methods for Chinese. The labels on the upper right of each key is Zhuyin (aka bopomofo). The lower right of each key is label for Chinese input method called Cangjie (倉頡).

Chinese Input Methods

To type Chinese, you need to use what's called “input method”, because there are not enough keys for each character to have 1 key.

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 methods are used by most Chinese, probably greater than 95% of all Chinese speakers, because it's a system anyone who speak standard Chinese can learn in a day.

For each character, there are usually more than five homonyms (different characters with the same sound), so sound based system pop up a selection to let you pick the right character. This makes sound based system slow. (but input systems today have statistical data that lets you input the sound of several characters such as a word or a phrase, and the system can often correctly guess which word/phrase you want, so you don't have to manually chose each character.)

Character shape based methods require learning, but is in general faster and more precise, because you don't have the homonym 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 Systems: Pinyin, Zhuyin

The most popular input methods are:

Both are sound based.

Pinyin input method is mostly used in China. Pinyin is a phonetic system, using English alphabets as phonetic symbols. Any USA keyboard can type pinyin. No special label is necessary on the keys.

Zhuyin input method is mostly used in Taiwan. Zhuyin is a phonetic system. It is almost the same as pinyin, except that it uses special symbols instead of English alphabets. (For example, here's first 4 zhuyin alphabets: ㄅ ㄆ ㄇ ㄈ, they correspond to pinyin's b p m f.) 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

(meaning “I, me”, pronounced “wo”)

in pinyin, you press w o.

Character Based Systems: Wubi, 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.

In Hong Kong, the most popular Chinese input method is Cangjie. (because Hong Kong people speaks Cantonese, they do not know standard Chinese pronunciation well, so they use shape based input.)

Both of wubi and cangjie 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.

The Most Popular Chinese Input Method

  1. pinyin → (sound based) used in China and around the world. Used by perhaps 90% of ALL Chinese speakers.
  2. zhuyin → (sound based) used mostly in Taiwan.
  3. wubi → (shape based) used mostly in China by some people.
  4. cangjie → (shape based) used mostly in Hong Kong, and by some people Taiwan.

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

Turn on Chinese Input

Microsoft Windows, Mac, Google gmail, all support many Chinese input methods.
