Base Claim:
1. A four-corner cut square Chinese character input method based on excellent code, comprising the steps of: assigning predesigned code table to corresponding keys of a keyboard; inputting Chinese Character according to four-corner coding of Chinese character by using the corresponding keys on the keyboard, an inputting rule of Chinese character coding including twenty cutting rules which comprise the characteristic of the excellent code combining with cutting skill, wherein the twenty cutting rules are regulated by first and second ones of the twenty cutting rules and include the following requirements: taking code in four-corner order: upper left corner, upper right corner, lower left corner and lower right corner, once a code is taken from a corner, the cutting for this corner is completed and will be continued in next corner, after a stroke is taken from a corner, the rest strokes stand still and wait to be cut for the next corner; using horizontal, vertical cutting lines or head-to-tail cutting lines and an outer frame of the Chinese character to constitute different squares including shapes of and -shaped cutting frames; each cutting square only contains one definite code; excellent codes are systematic and there are no superposed strokes and crossed strokes between excellent codes, matriculated code can be separated from other strokes and can separate other codes, each cutting square contains one code only, including the cutting squares of shapes of and -shaped cutting frames; red code is full-cut and fully matriculated when it is cut; two incomplete codes are allowed to share a common stroke, a cutting point exists in a middle section of a common stroke, a cutting line passes through the cutting point to separate the common stroke into two complete strokes, the cutting line is not allowed to cut strokes that have no cutting point; inserting or adding radical codes, or other radical codes lacking some strokes, in order to prevent overlap among the Chinese characters of same type, including: cutting skill is implemented by: understanding of the twenty cutting rules; grasping excellent code table; apart from considering original order of the strokes and the squares, black code is cut according to the following three cutting steps: first step: first cutting line is placed between two parallel opposite sides of the outer frame of the Chinese character and can be vertical or horizontal, including: if the first step fails or there is more than one code in the cutting square, the second step will be used; second step: first and second cutting lines which are vertical to each other and run across two parallel sides, there are more than one code in a rectangle formed by the first cutting line, the second cutting line is carried out by turning 90 degrees with respect to the first cutting line and runs between two parallel sides: one side is the first cutting line, and the other side is the side of the outer frame of the Chinese character, the code is taken from a small square which is closest to the cutting corner, including, the two cutting lines of the second step are characterized that: they all run across or are connected between two parallel sides; if the second step fails, the third step will be used; third step: curved cutting: at least two cutting lines which turn continuously 90 degrees with respect to one another and are characterized in that: at least one or more of the cutting lines doesn't run across two parallel sides and constitutes different kinds of shapes of or -shaped cutting frames, all curved cutting lines are red codes, including,

Claim 10:
10. The four-corner cut square Chinese character input method based on excellent code as claimed in claim 1 , wherein cutting rules No. 19-20 of the twenty cutting rules are explained as follows: moving a single code within a code cutting square which opens upward or downward out of the horizontal cutting line, the single code has a priority to be cut by straight cutting, including: if there is a horizontal stroke covering the open end of the code such as this cutting rule is not applicable. The special cutting rule is designed to solve a problem caused by whether the first code is within or outside the square of code in addition to the cutting rule No. 19 which is special cutting rule for code the present invention further has a normal cutting rule: including:
