我昔先君子，为公义林此。论儒摘寡要，太史固坐井。期公非敬知，力行福黎蠢。螭坳千载逢，凤池一跬近。独妍当众媸，隐忧触群愠。颇觉游梁倦，终成吊湘恨。声名出寒饿，圭组憎薄命。纶言表厄陈，衮札囊束笋。传家侈荣渥，尚足破孤愤。肠折八哀诗，涕堕五君咏。长歌饯公归，木脱
楚云朝暮蔽前峰，佳节寻芳已半空。三日薰炉沈蕙绿，一星春火并榆红。文鳞对掷回塘水，贺燕交飞翠幕风。怅忆沈斋题句罢，碎英无响坠华桐。
病躯终日困骄阳，正虑行行去路长。多谢天公怜此意，时飞疏雨作清凉。
罗襦绣袂香红，画堂中。细草平沙蕃马、小屏风卷罗幕，凭妆阁，思无穷。暮雨轻烟魂断、隔帘栊。
荷屋老子僧中龙，平生眼里无诸公。莫年愈觉气深稳，木寒霜净天无风。朅来精进复精进，焚香却扫大圆镜。数十万偈堆如山，从头一唱一加敬。波澜散入诸子中，华藏海与川源通。秋毫茧纸快收拾，百城烟水行无穷。善财再见文殊日，一臂黄金摩顶讫。选佛场中及第归，便是西来好消息。
淡淡秦云薄似罗，灞桥杨柳拂烟波。夕阳楼上山重叠，未抵愁春一倍多。
