                                                                                          行路难
                                                                                     作者：李白(唐)
                                                                        金樽清酒斗十千，玉盘珍羞值万钱。
                                                                        停杯投箸不能食，拔剑四顾心茫然。
                                                                        欲渡黄河冰塞川，将登太行雪满山。
                                                                        闲来垂钓碧溪上，忽复乘舟梦日边。
                                                                        行路难，行路难，多歧路，今安在？
                                                                        长风破浪会有时，直挂云帆济沧海。
