What is "white at night"? Who can answer it?

According to news reports, the words "night show" and "enzyme" seem to have nothing to do with each other, but in fact they have deep roots. Nowadays, with the popularity of "Night Show White", the relationship between the two is gradually becoming familiar. As a night owl, I feel a little behind the times without "night white" self-defense. According to the reporter's investigation, "night white" is the name of an enzyme product. The product name is Aisha International Enzyme. Because its packaging theme is white, it is called Xiaobai by people in the industry.
