杜甫客居云安县期间，与之交往而情谊甚厚者当数郑贲和常徵君二人。郑贲乃遭逢世乱而“窜身”云安的青年士子，委身是地，甘为卑官，捷径邪至而不忍投步；徵君常某虽曾徵入朝堂，然风尘晚年，为外吏：“藏身”开州，处境则颇为艰难。郑、常二人，一少一老，与杜甫的关系，一为新知，一为故交。在杜甫羁身异处，卧病不起的日子里，一在近旁，与诗人相亲相近，多有关照；一位则忧及故人病情，特从开州远道赶来探望，此后且时有来书。二人与杜甫，相交相知，其关系均非同一般，故而诗人所写《赠郑十八贲》、《寄常徵君》等诗篇实乃诗人真情之流露，绝不可以率意之笔视之。本文就以上诸多内容，细加考释，并附带谈谈诗人离云赴夔的客观原因，以求正于学界。 Du Fu guest Yunan County, during the interaction with the relationship between those who are very fond of Zheng Ben and often Zheng Jun two.
