                                                                                             宋•俞桂
                                                                    西风萧瑟入船窗，送客离愁酒满缸。   
                                                                    要记此时分袂处，暮烟微雨过松江。
                                                                                          别董大  

                                                                                         唐•高适
                                                                  千里黄云白日曛，北风吹雁雪纷纷。  
                                                                  莫愁前路无知己，天下谁人不识君?
                                                        【注】袂：袖子。诗中“分袂”是分别的意思。
