barren land

Land development for people of Chūka at that time.
It would have been "good deeds".

"A person become the ruler who receives the mandate of heaven.　
Only he receives an obligation to govern this world from heaven."　

Previous of the Xia dynasty,rulers of mythology era of China.
（禹 of the Xia dynasty founder also including.)
They were the embodiment exactly of this thought.

They ruled the world who received the mandate of heaven.
And they have passed the dominion to the person who received the mandate of heaven then.

Of course this is episode of mythology era.
In short，they are gods.

Well，one of the qualifications they received the mandate of heaven.　
It was the ability of flood control.
　
In the trial period(?)，he changed wasteland to fertile land by his ability.
The results，Yield of grain increased by it.
Of course，population also increased.
People began to live a peaceful life.

And he were able to receive the mandate of heaven.
　
To the contrary，person (god) who failed to flood control.
He was chased from the position of god.

North of Chūka at that time.　
Vast grassland had spread there.
Nomads people lived there with livestock.

Grass is a livestock feed.
They gave it little by little to livestock while moving.

With the development of land，people of Chūka have been advanced their living area to there.
Grassland was a land of vast unattended for them.
They're people of farming.　
Of course they plowed grassland.

But soil of grassland was very thin.
Plowed soil.
It was blown away in the wind of the grassland.

Then bedrock was exposure.
As a corollary， its grassland became a desert.
　
"to play the desert to the grassland."
It was impossible by the action of nature.
And it was also impossible with the technology of the time.

"They are barbarians.
Grassland gives living creatures a great boon.
Our life are satisfied by it.
This is the boon of heaven.

But they plow its grassland.
And they change it to barren land."
　
Such stele of nomad people.
It still remains.
