Draft:Ziranma

The Ziranma ( input method is a Chinese input method, originally designed by Zhou Zhinong in the 1980s with continuous minor upgrades until 2009.

How it works
Ziranma makes use of both phonetic and shape information of Chinese characters. The phonetic part, Ziranma shuangpin, is a condensed form of toneless pronunciation of a character using only two latters. The shape part, Ziranma shape code, describes the shape of a character in also two letters. Each character is encoded as four letters in total.
