Abstract: The analogy of pen with weapons is a phenomenon rich in hierarchy and systematicness in ancient literary criticism. It comes from the ancients' pursuit of words' real power, the habits of mind of metaphor with objects, the influence of war craft on art theory and the literati's hope of being well-versed in both polite letters and martial arts. It has kinds of existence forms and concludes words, literary form, atmosphere and ornate wording and so on. Besides, the analysis of the analogy of pen with weapons' production will guide us to a deeper system of literary criticism, which is the analogy system of literati's writing with craftsmen's crafting. The generation of this system is closely connected with the change of the situation of comments on literati and the formalization of literature.
