There are 28 topics in this book. Most of the grammar points of the HSK Syllabus (elementary and intermediate Chinese) are covered. The emphasis is placed on the most important grammar points and typical difficulties of teaching Chinese as a foreign language, which is handy and precisely designed. Each topic has similar exercises to those found in the HSK and answers for the readers to check. Idioms, set phrases and colloquial patterns required by the HSK Syllabus are attached at the end of the book.
