Based on the corpus of Teaching Chinese as a Second Language, the paper analyzes the features and levels of the contextual information in Chinese teaching, and discusses the tagging system of contextual information. The meanings and the main elements of contextual information tagging are proposed, including emotions and attitudes, semantic functions of questions and answers, and thematic information of passages. It is argued that the tagging issue should be discussed according to different language levels. In addition, with tapping experiments and statistical analyses, the feasibility of the framework in tagging the corpus and the application of the tagging information in the practice and research of Teaching Chinese as Secondary Language are presented.
