The learning errors in this book are picked from the author's collection of errors of Chinese learners at above intermediate level. These errors are of high frequency and difficult for self-correction, and occur in the learning of Chinese learners from different countries. Organized into 30 categories (the corresponding 30 chapters) according to the grammatical functions, the errors are described in detail and contrasted with the correct ones comprehensively. The author tries to illustrate the sources of the errors as clearly as possible and therefore explore the most effective teaching methods for error correction.
