Put the yellow one in the middle first, and make a yellow cross on it, that is, put the other color blocks in the corresponding position. Then put the yellow corner back, let the middle side block be put back, and adjust the yellow corner block around the cross. At this time, the yellow is out of position with the side. According to the formula, the yellow block is positioned at the four corners, and finally the edge color block is adjusted to the corresponding position, and it is completed.
