In ancient times, literary questions and answers were often called " literary inquiries " or " literary questions and answers." These terms could be traced back to ancient China, when people began to use books to record and answer literary questions, such as the question and answer section in The Analects of Confucius and the consultation section in National Policy. These books usually included answers and explanations to various questions, as well as analysis and discussion of these questions. Therefore, in ancient literature, question-and-answer was regarded as an important literary research and creative activity.
