Pinyin, defined as the Chinese phonetic alphabet, is the official romanization of standard Chinese words(Characters) in mainland China. From ancient to modern, Chinese is the language without a direct alphabet for its characters(so-called Hanzi), that’s why Hanyu Pinyin is one of the vital tools to effectively transcribe it with each syllable corresponding distinct meaning, including the Latin Alphabet(initials and finals) and a tone marker (one of four). The Chinese-language combining-sounds alphabet is the verifying “spell pronunciation” for teaching Chinese written words and helps people learn the Mandarin pronunciation.
