【诗文】:
有客西北逐,驱马次太原。太原有佳人,神艳照行云。
座上转横波,流光注夫君。夫君意荡漾,即日相交欢。
定情非一词,结念誓青山。生死不变易,中诚无间言。
此为太学徒,彼属北府官。中夜欲相从,严城限军门。
白日欲同居,君畏仁人闻。忽如陇头水,坐作东西分。
惊离肠千结,滴泪眼双昏。本达京师回,贺期相追攀。
宿约始乖阻,彼忧已缠绵。高髻若黄鹂,危鬓如玉蝉。
纤手自整理,剪刀断其根。柔情托侍儿,为我遗所欢。
所欢使者来,侍儿因复前。抆泪取遗寄,深诚祈为传。
封来赠君子,愿言慰穷泉。使者回复命,迟迟蓄悲酸。
詹生喜言旋,倒履走迎门。长跪听未毕,惊伤涕涟涟。
不饮亦不食,哀心百千端。襟情一夕空,精爽旦日残。
哀哉浩然气,溃散归化元。短生虽别离,长夜无阻难。
双魂终会合,两剑遂蜿蜒。丈夫早通脱,巧笑安能干。
防身本苦节,一去何由还。后生莫沈迷,沈迷丧其真。
