I'm curious which kings are seen as Good Kings and which Bad Kings and how it maps to like, what they were thought of at the time, because we never see an in between so so king. Maybe those just don't get poems.

Anyway, Baike says this was about a four year drought during the reign of Zhou Xuan wang, but also says it was written by someone else, who is unknown.

Baike also mentions that:
Of the remnant of Zhou, among the black-haired people,
There will not be half a man left;
Was early considered as a model of exaggeration / rhetoric.
