Hanyinzi is an adaptation of Hangul to Mandarin phonetics by Ben Lowsen. As much as possible, native Korean letter forms are preserved. The necessary changes are as follows (Mandarin sounds rendered in Pinyin):
In writing, Hanyinzi acts as much as possible as possible as Hangul, that is written in equally-sized syllables with ieung (ng) indicating a syllable without a consonant initial. The biggest difference is the addition of tone marks beneath the jamo. The sample text should clarify most other usage questions. As for purpose, the creator's intent was to use a native east Asian alphabet to display the sounds of Mandarin both efficiently and elegantly. One immediate application might be for Korean speakers learning Chinese.
