Hanzi characters are used in Chinese writing system for representing syllables of spoken Chinese. A Hanzi character does not represent phonemes and tones directly. To be considered literate in Chinese, a person has to remember the pronunciations of thousands complicated characters largely by rote. A Chinese student typically needs to spend years on this tedious task; for an adult, especially an adult learning Chinese as a second language, Hanzi characters represent an almost insurmountable barrier on the way to real proficiency of written and spoken Chinese.
Pinyin uses Latin alphabet for transcribing the Mandarin pronunciations of Hanzi characters, and uses diacritics for marking the tones. A Hanzi character is pronounced as one pinyin syllable, which usually includes one or zero initial and one final. Native speakers of Roman languages often find learning Chinese with Pinyin very comfortable.
Pinyinz simplified pinyin in several aspects: It replaced Ü with V, squeezed the multi letter initials and finals into new single letters, omitted tone diacritics as well as complicated rules and exceptions, replaced final the O in BO, PO, MO, FO, WO with UO and replace the final I in ZHI, CHI, SHI, RI, ZI, CI, SI with a silensed tone mark for acoustic fidelity.
Pinyinz is so simple that people can learn pinyinz in a single day. For a person who has already learned pinyin, pinyinz can be learned in less than one hour.
