Having embarked of the huge task of learning this fascinating and challenging language, with language tapes, text books and all the Paraphernalia, I keep falling back to this well constructed tome. It has an admitedly limited vocabulary however it goes beyond being a simple dictionary by being a guide to usage.the grammar notes are good, and a further plus the Chinese characters are for the most part large enough to see. Something most books neglect. this book is in the living room by day, and the bedroom by night. I have two other great dictionaries for a more extensive vocabulary, however, this is THE essential first dictionary, well done all.
