111 shapes are defined as necessary to reproduce all the patterns forming characters.
They are divided in 24 groups represented by one Chinese characters
(lead sign, or main sign) and linked to one of 24 letters of
usual keyboard, in a
meaningful way easy to remember..
retrieve characters: type 1 to 5 of the 24 letters matching the shapes of
the desired character, in respect of the other rules of the method.
They are important, basic characters, like Sun
the Five elements: Metal
Wood木 , Water
etc., they are therefore very easy to remember.
Their corresponding code-letter on the keyboard
is also easy to remember: the above 7 signs correspond to the code-letters
AB, C D E F G.
Within each "part" of a character (called
"unit" in CJ),
signs are accounted in a sequence similar to the stroke
order for writing
top to bottom
--from left to right
the outside to the inside
They are regrouped (by variable number s of one
to 7) to each of the Main Signs which represent its own shape plus that of
the secondary signs in its group.
Secondary sign shapes are not difficult to
remember either because their shapes derive from that of the lead sign they
are assigned to.
There are 3 guide lines on how to delineate
the signs to match their shapes to characters shapes:
1- Rule of completeness: character
shapes are allocated to form the most complete sign
2- Avoid joining of signs at an angle
of character shapes.
3-In principle, sign lines must not
cross over other sign lines, especially enclosed shapes
code-letters to get a character are 1 to 5 depending on whether the
character has 1 or 2 or 3 parts (units):
-single unit: gets maximum of 4 codes for 1st,
2sd, 3rd, & last signs;
-Two unit and 3 unit characters get 5 codes
maximum, divided in between their units:
-2 max for the 1st unit;
-2 max for the 2sd unit;
-1 or 2 for the last unit
some characters, units are made by the integration of signs, or blocks of
signs. This integration reduces the number of possible parts (units) of a
character of a maximum of three.
1-Some group of strokes are always represented
by the same two codes;
2-Some groups of strokes are considered as a
unit when they are in certain position within the characters
3- character shapes that enclose other shapes
are preferred for input.
4--characters with some shapes considered
intricate have a simplified predefined code.
