                                                                                                      山寺夜起
                                                                                                    （清）江湜
                                                                         月升岩石巅，下照一溪烟。烟色如云白，流来野寺前。
                                                                         开门惜夜景，矫首看霜天。谁见无家客，山中独不眠。
