Five-Stroke Theorem

Chen Li-Fu first invented "5-stroke method" to search
a Chinese character in a dictionary in 1920's.

The five strokes are :

- | / . Z

Use first 4 strokes and last 1 stroke to identify a character.

Chang Chunn published 5-stroke searching method for XINHUA ZIDIAN
(Hsing-Hwa dictionary) in 1980's in Beijing.

He gave me a copy of his work in 1996 when he came to
Sacramento CA to visit his brother Dr. Chang Poon.
