What is the poetic meaning of Han Yuefu?

Translation

1) There are green sunflowers in the garden,

the dew will be dried by the morning sun.

Spring spreads the hope of happiness all over the earth,

All living things are showing prosperity and vitality.

I'm just worried about the coming of rustling autumn.

The leaves will turn yellow and the grass will wither and die.

Thousands of rivers are rushing eastward and flowing into the sea.

When can they flow westward again?

People are the same. If you don’t work hard when you are young, you will only regret it when you are old.

2) There are green vegetables growing in the yard.

As soon as the sun comes out, the dew on the vegetable leaves will be dried.

The warm spring is spreading her blessings.

Everything in nature shines on the wall.

I often worry about the coming of autumn.

The flowers and leaves are all withered.

Thousands of rivers flow toward the East China Sea.

When can we return to the west?

Not working hard when you are young and strong.

When you are old and frail, you can only feel sad in vain.
