Hanyu Pinyin for Mandarin Speakers.
To assist with the learning of pronunciation and to allow you to note down and keep track of language more easily, we teach, along with characters, the official phonetically based writing system known as Hanyu pinyin. Students with no knowledge of Hanyu Pinyin can visit http://web.mit.edu/~jinzhang/www/pinyin to learn it.
The differences between jianti and fanti characters are not as significant as might be imagined, so we will get used to reading both. For writing, you may choose either one.
