《文心雕龙·辨骚》
屈、宋所抒写的怨抑的情感，使读者为之痛苦而深深地感动；他们叙述的离情别绪，也使读者感到悲哀而难以忍受。他们谈到山水的时候，人们可以从文章音节悬想到岩壑的形貌；他们讲到四季气节的地方，人们可以从文章辞采看到时光的变迁。
故其叙情怨，则郁伊而易感；述离居，则怆怏而难怀；论山水，则循声而得貌；言节侯，则披文而见时。
Qu and Song's expression of sorrow and depression causes readers to feel tormented and deeply moved; their narratives of parting sadness and yearning also plunge readers into unbearable sorrow. When they talk about landscapes and mountains, people can visualize the form of mountains and valleys from the musicality in the writing; when they speak of the four seasons, people can see the changing of time from the style and rhetoric of the text.
