north

Poets on Horqin Grassland

Say to me:

"North sorrow."

Not bad.

The north is sad.

Blow from the outside of the plug.

Desert wind,

Has swept away the green of life in the north.

And the glory of time

-Dark grayish yellow.

Covered with a layer of sand fog that can't be opened;

That day, the roar that rushed to the edge.

Brought terror.

like mad

Sweep the floor;

Desert Yuan Ye

Frozen in the cold wind of December,

Villages, hillsides, river banks,

Collapsed walls and deserted graves

Covered with earthy melancholy ...

Lonely pedestrians,

Upper body leaning forward

Cover your cheeks with your hands,

In the wind and sand

dyspnea; respiratory distress; breathing difficulties

one by one

Struggle forward ...

A few donkeys

-With sad eyes.

A beast with tired ears,

Carrying land

The weight of pain,

Their tired footsteps

go slow

the north

A long and lonely road ...

Those rivers have dried up long ago.

The bottom of the river was also rutted.

The land and people in the north

yearn for

The fountain that nourishes life!

Withered tree

And low-rise residential buildings

Sparsely, darkly

Scattered under the gloomy sky;

In the sky,

Can't see the sun,

Only geese form a large group.

A flock of wild geese

Flap black wings

Shout out their words and sadness,

Escape from this desolate area

Escape to

The south, where the green covers the sky, has disappeared. ...

The north is sad.

Yellow River in Wan Li

Surging with turbid waves

Go to the vast north

Pour out disasters and misfortunes;

And the wind and frost of the age

describe

The vast north

Poverty and hunger.

5 and me

-This passenger from the south,

But love this sad northland.

blowing sand

And air conditioning to the bones.

Never let me curse;

I love this sad land,

An endless desert.

It also aroused my respect.

-I see

Our ancestors

Lead a flock of sheep

Play the flute

Immersed in this desert dusk;

We are moving forward.

In the ancient soft loess layer

Buried with the bones of our ancestors,

This land was reclaimed by them.

Thousands of years.

They're here.

They defended the land by fighting against the nature that hit them.

Never been humiliated,

They are dead.

Leave us the land—

I love this sad land,

Its vast and barren land

Bring us simple words

In a broad posture,

I believe this kind of speech and gesture.

Live strong in this land.

Never perish;

I love this sad land,

Ancient land

-This land

Raised the people I love.

The hardest thing in the world

The oldest race.
