                                                                                     酬乐天扬州初逢席上见赠
                                                                                                  刘禹锡
                                                   巴山楚水凄凉地，二十三年弃置身。怀旧空吟闻笛赋，到乡翻似烂柯人。
                                                   沉舟侧畔千帆过，病树前头万木春。今日听君歌一曲，暂凭杯酒长精神。
