The Changjie input method is a system by which Chinese characters can be entered into a computer using a standard keyboard.

Changjie is based on the graphological aspect of the characters: each basic, graphical unit is represented by a basic character component, 24 in all, each mapped to a particular letter key on a standard QWERTY keyboard. An additional “difficult character” function is mapped to the X key.

Within the keystroke-to-character representations, there are four subsections of characters: Philosophical Set (corresponding to the letters ‘A’ to ‘G’ and representing the sun, the moon, gold, wood, water, fire and the earth), Strokes Set (corresponding to the letters ‘H’ to ‘N’ and representing the brief and subtle strokes), Body-Related Set (corresponding to the letters ‘O’ to ‘R’ and representing human, heart, hand and mouth) and Shapes Set (corresponding to the letters ‘S’ to ‘Y’ and representing complex and encompassing character forms).
