雨中花 仆自幼刻意林壑，不耐俗事，懒慢之【诗文】：能自克。志复疏怯，嗜酒好睡。遇乘高履危，动辄有畏。道逢达官稠人，则便欲退缩。其与人交，无贤不肖，往往率情任实，不留机心。自惟至熟，使之久与世接，所谓不有外难，当有内病，故谋为早退闲居之乐。长大以来，遭时多故，一行作吏，从事於簿书鞍马间，违己交病，不堪其忧。求田问舍，遑遑於四方，殊未见会心处。闻山阳间，魏晋诸贤故居，风气清和，水竹葱 。方今天壤间，盖第一胜绝之境，有意卜筑於斯，雅咏玄虚，不谈世事，起其流风遗躅。故自丙辰丁巳以来，三求官河内，经营三径，遂将终焉。事与愿违，俯仰一纪，劳生愈甚，吊影自怜。然而触於事物，感今怀昔，考其见於赋咏者，实未始一日而忘。李君不愚，作掾天台，出佐是郡，因其行也，赋乐府长短句，以叙鄙怀。行春胜日，物彩照人，为予择稚秀者，以雨中花歌之，使清泉白石，闻我心曲，庶几他日，不嗜酒偏怜风竹，晋客神清，多寄虚玄。有山阳遗迹，水石高寒。曾为幽栖起本，几求方外微官。谩蹉跎十载，还羡君侯，左驾朱。山村霰雪，竹外花明，瘦梅半树斓斑。溪路转、青帘佳处，便是萧闲。寄谢王君精爽，摩挲森碧琅。个中著我，储风养月，先报平安。【注释】：【出处】：
