The whole set of books consists of 9 volumes, divided into "Elementary Spoken Chinese" (I, II and advanced content), "Intermediate Spoken Chinese" (I, II and advanced content), and "Advanced Spoken Chinese" (I, II and advanced content). The nine textbooks select appropriate scenarios and functions to cultivate students' ability to communicate in oral Chinese gradually. "Elementary Spoken Chinese" mainly studies commonly used oral sentence patterns, simple dialogues, and paragraph expressions; "Intermediate Spoken Chinese" runs through several main characters throughout, giving them certain personality traits and language styles and showing different aspects of Chinese social life. "Advanced Spoken Chinese" takes a typical Chinese family as the main line unfolds the story scene in a script-like form, discusses hot topics, and shows multiple aspects of Chinese families and society.
