“On the seventh day of the Seventh-month, in the Palace of Long Life,
We told each other secretly in the quiet midnight world
That we wished to fly in heaven, two birds with the wings of one,
And to grow together on the earth, two branches of one tree.”
Earth endures, heaven endures; some time both shall end,
While this unending sorrow goes on and on forever.
— From “A Song of Unending Sorrow”, Bai Juyi (772-846 AD)
