11. A method for moving a Chinese input candidate word box, comprising: creating a candidate word box and drawing the candidate word box in a position within a range of a screen; analyzing and calculating a moving distance after generating an input signal through directly dragging the candidate word box by a user or through operating a direction key or a direction soft key by the user to move the candidate word box; and destroying the candidate word box in situ when the moving distance is not beyond the range of the screen, and redrawing a candidate word box in a new position which the candidate word box is moved to, when the moving distance is beyond the range of the screen, recording a distance between an initial position of the candidate word box and an edge of the screen in the direction as the moving distance, when the input signals are generated by direct dragging of the user, calculating the moving distances of the candidate word box in the horizontal and vertical directions according to a difference between a horizontal coordinate value of the initial position of before dragging and a horizontal coordinate value of the initial position after dragging and a difference between a vertical coordinate value of the initial position before dragging and a vertical coordinate value of the initial position after dragging, and respectively multiplying a horizontal moving distance and a vertical moving distance by a conversion coefficient to slow down a moving speed during the dragging and obtain the moving distances of the candidate word box, wherein the step of calculating the moving distance comprises: recording the pressed direction keys and a number of times of pressing the direction keys when input signals are generated through operating the direction keys or the direction soft keys to move the candidate word box, and calculating the moving distance according to the number of times of pressing the direction keys; and recording initial position information when effective input signals are generated by direct dragging of the user, and calculating the moving distances in the horizontal and vertical directions according to the initial position information, further comprising: when the input signals are generated through operating the direction keys or direction soft keys to move the candidate word box, correspondingly moving a set step length each time when operating the direction key or the direction soft key once.
