After reading the sage books for so many years, you know that the words "black and white don't argue" come from "confusing black and white" and "The Book of the Later Han Dynasty Yang Zhenchuan" written by Ye Fan in the Southern Song Dynasty: "White and black are confused, and clarity and turbidity are of the same origin." .

"There is no distinction between right and wrong" comes from Liu An's "Huai Nan Zi Xiu Wu Xun" in the Western Han Dynasty: "I recite it when quoting, and the distinction between right and wrong is unclear."

Confusing black and white is blurring the boundaries. Deliberately saying that black is white and white is black creates confusion. It refers to deliberately creating confusion and confusing people.

Right and wrong are indistinguishable.
