It is a simplified stroke-based sorting method free of stroke counting and grouping.
In this joint index the user can look up a Chinese character alphabetically to find its pinyin and Unicode, in addition to the page numbers in the two popular dictionaries.
[5] In the Oxford Advanced Learner's Dictionary, the word alphabet is defined as "a set of letters or symbols in a fixed order used for writing a language".

The code duplicating rate (重码率) of the traditional method on the 20,902 CJK characters set is 10.31%.
The maximal number of characters sharing a code is reduced to 4, such as 甲 曱 叶 申.
(Duplicating code characters, i.e., characters sharing a stroke order code, are sorted by the positions of the starting and ending points of corresponding strokes in the order of higher before lower and left before right.
