If you use a third-order Rubik's cube to spell, generally speaking, it is to adjust the color block of one face, keep the other faces still, and then put them together.

Judging from the colors in the above picture, white and yellow are the highlights of facial skin, red and orange are the shadows and dark parts, and blue is the main color of hair. . . .

In fact, the pattern is very unclear, if the characters are not obvious in facial features, such as hairstyle and face shape. . . That's really hard to identify. . . (In addition: it is estimated that the photos should be processed by the filter effect of the picture software to form obvious color blocks, which is more convenient to "express" with the Rubik's Cube)
