                                                                                         送李副使赴碛西①官军
                                                                                               ［唐］岑参
                                                                           火山六月应更热，赤亭②道口行人绝。
                                                                           知君惯度祁连城③，岂能愁见轮台月。
                                                                           脱鞍暂入酒家垆④，送军万里西击胡。
                                                                           功名只向马上取，真是英雄一丈夫。
