[Idiom] 'this being a metaphor for the kingdom'

[yeju]

'whichever child has the largest, most beautiful plant will earn the throne;this being a metaphor for a kingdom.'
I don't know what it means.

 

[bhaisahab]

Where did you find this?

 

[yeju]

I can't find site that i read it on
Is it not grammatical?

 

[bhaisahab]

It's not a question of whether or not it is grammatical. You want to know what it means and without context it's impossible to say.

 

[Tdol]

The plants symbolically represent the kingdom, so the child who produces the best plant will earn the throne as they have shown that they can care best for the plant.

However, this is a strange sentence.
