前不見古人,後不見來者。
念天地之悠悠,獨愴然而涕下。
By Chen Zi'ang
Witness not the sages of the past,
Perceive not the wise of the future,
Reflecting on heaven and earth eternal,
Tears flowing down I lament in loneliness.
Another version:
ON A GATE-TOWER AT YUZHOU
Where, before me, are the ages that have gone?
And where, behind me, are the coming generations?
I think of heaven and earth, without limit, without end,
And I am all alone and my tears fall down.
