                                                                                        丑奴儿.书博山道中壁
                                                                                                 辛弃疾
                                                                 少年不识愁滋味，爱上层楼。爱上层楼，为赋新词强说愁。
                                                                 而今识尽愁滋味，欲说还休。欲说还休，却道天凉好个秋。
