Hanyu Pinyin (汉语拼音) is the official romanization system for Standard Chinese.
Tones aside, there are two parts to every Chinese character – Sound (声母) and Rhythm (韵母), also known as the Initial and Final to English speakers. Although these combinations are made up of Latin alphabets, they do not always sound like the English pronunciations that we are accustomed to.
“a” Finals : a / ai / an / ang / ao
“o” Finals : o / ong / ou
“e” Finals : e / ei / en / eng / er
“ü” Finals : ü / üan / üe / ün – the most confusing page!
PS: The first version was printed and published in A Little Daily Dose: Discovering Chinese Characters Through Short Stories while I am currently refining and updating this online version. I am determined to find the closest English word for every Hanyu Pinyin anomaly.
