The Cang Jie Method codification of characters is based on their graphic nature: so, the retrieval of characters is done according to their shapes and structure, not according to their phonetic representation.
Therefore, the Cang Jie Method contains two ingredients :
The use these two ingredients is simple in principle:
1- Match the signs-shapes to the shapes forming the characters.
2- Follow the "rules of selection" to choose the signs whose corresponding letters form the code of the character and will have to be keyed in to get the character.
3- Type in the code-letters corresponding to the chosen signs and ... the character will appear on the screen!
ILLUSTRATION 1: suppose you need to type the character
In CangJie, the shape "" (田) on the top of this character is represented by the letter W, and the shape "" "月" is represented by the letter B. In this character, the two CJ shapes it is made of have to be inputted. In more complex characters, as will be seen later, many shapes are "skipped".
To know more about the essential principles of the CJ Method, and to compare them with the phonetic input methods please refer to the INTRODUCTION of the CJ book (download a zipped pdf file: you will need Acrobat Reader). You can print it and read it at ease. (It also explains the advantages of CJ and how you can type simplified characters used in Mainland China and Singapore following the same principles and rules as for for typing traditional characters used in Taiwan and Hong Kong).
