Write two poems about heaven and earth.

The earth endures, and the sky endures; One day both will end, and this endless sadness will last forever. Bai Juyi's Song of Eternal Sorrow

There is no mausoleum in the mountains, the river is exhausted, there is Lei Zhen in winter, and there is rain and snow in summer. Only when heaven and earth are in harmony can we dare to be with you!

The Book of Songs

Have you seen how the water of the Yellow River flows from the sky to the sea and never returns to Li Bai?

In heaven, I wish I were a wing bird, growing together on the earth, two branches of a tree. Bai Juyi's Song of Eternal Sorrow.
