What does Heitao's "Premonition" mean?

A premonition is a feeling you have before something happens.

Generally speaking, this is a very mysterious feeling, and it is difficult to grasp whether it actually exists. Black pottery was born in the Neolithic Age in China. The ancient Chinese pottery making technique is as black as lacquer. It has the reputation of being as loud as a sound, as thin as paper, as bright as a mirror, and as hard as porcelain. They have been found in the Daxi Culture, Qujialing Culture, and Longshan Cultural sites, among which the Dawenkou Culture is the earliest, dating back about 6,000 years.
