                                                                                                   金陵怀古
                                                                                               〔唐〕刘禹锡
                                                                                      潮满冶城^①渚，日斜征虏亭^②。
                                                                                      蔡洲^③新草绿，幕府^④旧烟青。
                                                                                      兴废由人事，山川空地形。
                                                                                      后庭花一曲，幽怨不堪听。
