Black history refers to the exposure of photos of senior high school students before 66, but at that time, 66 students were only interested in learning and didn't wear makeup, even though they didn't dress themselves up in the college entrance examination, so they looked less beautiful and a little dark. The editor of their station A called it black history just to attract attention, and 66 was very sad. Don't let me see that editor at station A, I'll cut him anyway.
