Pinyin
Pinyin is a system of
romanization (phonemic
notation and
transcription to Roman
script) for
Standard Mandarin, where pin
means "spell" and yin means
"sound". The most
common variant of pinyin in use
is called Hanyu Pinyin (Simplified
Chinese: 汉语拼音,
Traditional Chinese. By
letting Roman characters refer
to specific Chinese sounds,
pinyin produces a compact and
accurate romanization, which is
convenient for native Chinese
speakers and scholars.
