Long song (Han Yuefu Folk Song)

The trees in the garden are lush, and the crystal dew rises in the sun.

Spring fills the earth with hope, and everything presents a scene of prosperity.

I am always afraid that when the cold autumn comes, the trees in Ye Er will turn yellow and the grass will wither.

The river runs to the sea, and when will it return to the west?

A lazy youth, a lousy age.
