蔣緯國
The input method was invented in 1976 by Chu Bong-Foo, and named after Cangjie (Tsang-chieh), the mythological inventor of the Chinese writing system, at the suggestion of Chiang Wei-kuo, the former Defense Minister of Taiwan. Chu Bong-Foo released the patent for Cangjie in 1982, as he thought that the method should belong to Chinese cultural heritage. Therefore, Cangjie has become open-source software and is on every computer system that supports traditional Chinese characters, and it has been extended so that Cangjie is compatible with the simplified Chinese character set.
