on the same day

"Confucius said.
Two sun never ascended on the same day.
As well，two kings never exist on the same day."

About 100 years later from the death of Confucius.
Words like this seems to came to be told by the people of Confucian scholar as the words of Confucius.
　
"A person become the ruler of the world who receives the mandate of heaven.　
Only he receives an obligation to govern this from heaven."

This was associated with this thought of course.
　
"The man who get to the throne is like this."　

And in order to clarify this thought，the achievements (legend) of Yao and Shun seems to have formed clearly at that time.

Note:Yao and Shun are persons who did not hereditary the throne of course.
　
　
・・・・・・・・・
　
　
Confucius did not talk very little about the divine realm.
Confucian scholar after Confucius had follow it to basically.

But they talked about Yao and Shun in order to clarify the teachings of Confucius (they think).
Yao and Shun are gods.
So this was one step into the divine realm.
This may have been acted contrary to the teachings of Confucius.

However， they probably took that action to dare.

Legend of Yao and Shun.
As previously mentioned，it seems to have formed clearly in this period.
(The era of survival of the fittest.)

But iffy lore of Yao and Shun
It may have existed from previous.

Those in power.
And they might had justify their actions by it.

"The mandate of heaven to the ruler.
It is not like that，never.
We do not leave it to their arbitrariness."

Therefore、some confucian scholar might be tried to clarify its definition.
　
They sift through the folklore of many.
And they were allowed to fruition in a single personality.

Confucian scholar of the most spearhead of such an idea.
It seems to had been Mencius.
 　
"Nuisances."　

As a corollary，his school seems to have been little anti-establishment.
