A road to black, as the saying goes, describes that in order to achieve a certain goal, it will go to the end without hesitation. There are both positive and negative meanings.

Explanation: At the end of hutong, China implemented the "Li Fang system" in ancient times, and all hutongs were closed. So a road is dark, that is, it doesn't turn back or turn.

Black: End.

Origin: Wei Wei's Oriental consists of five chapters.

Ex.: He is determined to go all the way to the dark, and he must be the enemy of the people.
