This paper is meant, based on some of the key concepts of Xun Zi, to ask a few questions: What is the question consciousness of Xun Zi the author or Xun Zi the work? What is the fundamental concern of Xun Zi and Xun Zi? What's the purpose of Xun Zi's doctrine? Does Xun Zi's doctrine have its own epistemology? If it does, what kind of epistemology is it? Through asking these questions, we work out an interpretative structure of Xun Zi's doctrine, that is, a construction of Xun's moral epistemology. Moreover, we would reflect upon and confirm the contemporary meaning that such an epistemology is possessed with.
