|Almost a thousand years have passed since the heyday of King Cheng
and King Kang, and many rulers having tried to attain the same glory.
But this golden era of peace and prosperity never returned. Why has this
been so? It is because rulers have forsaken the law and moral
standards, and have instead pursued selfish desires, spoiling themselves
with extravagance, and totally neglecting the practice of benevolence
and righteousness.Scroll 19: Han Shu, Vol. 7|
