                                                                                              枫桥夜泊    张继
                                                                                              月落乌啼霜满天，

                                                                                              江枫渔火对愁眠。

                                                                                              姑苏城外寒山寺，

                                                                                              夜半钟声到客船。
                                                                                           

                                                                                               次北固山下  王湾
                                                                                         客路青山外，行舟绿水前。

                                                                                         潮平两岸阔，风正一帆悬。
                                                                                         海日生残夜，江春入旧年。

                                                                                         乡书何处达，归雁洛阳边。
