"Before me, where was the past era? Behind me, where are the future generations? "The ancients here refer to wise monarchs who were kind to virtuous corporal in ancient times. Qiu Ji's Visit to the Ancient Tibetan Land-dweller and Youzhou Tower are works of the same period, and their contents can be used for reference. Seven songs, "Qiu Ji visited the ancient times and gave it to Lu Jushi for hiding", expressed infinite admiration for Yan Zhaowang's courtesy to Le Yi and Guo Kun and Yan Taizidan's courtesy to Tian Guang during the Warring States Period. However, like Yan Zhaowang, the sages of the previous generation are no longer visible, and the sages of later generations have no time to visit them. They are really out of place; When I stepped onto the stage and looked out, I saw the vast universe, which was eternal. I can't help feeling lonely, and my sadness comes from it, and I burst into tears. Therefore, "the mountains and rivers are still the same, and the characters are different" to express their "unfortunate birth" lament. It is inevitable that there is sorrow of the times here, but there are also poets' hatred of the dirty poetry world. Poets can't see the ancient sages, and the ancients didn't have time to see poets; The poet can't see the future Yingjie, and the future Yingjie can't see the poet. What poets can see, what they can see, is only the present era. This poem expresses the poet's frustrated situation and lonely and depressed mood in a generous and sad style. This kind of sadness is often caused by many talented people in the old society, so it is widely praised by scholars.
