A note about pronunciation: The dialogue above includes the pinyin romanization of the text. The advantage of pinyin for English speakers is that it uses the familiar symbols of the Latin alphabet. The disadvantage is that English speakers are easily deceived into thinking these familiar symbols represent the same sounds they do in English. They don't. That said, pinyin can be a useful system to learn, but you must rely on your ears first, eyes second.

Don't expect to be able to pronounce anything just by reading the pinyin; the romanization is just a reference to jog your memory. The language exists primarily in its sounds, which is why daily listening and imitation practice is so important.
