How to restore the messy Rubik's cube?

1. Prepare a disturbed Rubik's cube, facing the white square above.

2. Make a white cross at the top, put the squares of other colors in the corresponding positions, and then put the white corner blocks in place.

3. Let the middle side block return, turn the white side down and find the red and green side blocks. If the red and green edges are on the top floor, turn the top floor clockwise.

4. Turn the Rubik's Cube according to the formula, so that the side block is in place. Pay attention to the units of blocks, each block has its specific position and orientation.

5. If the red and green edge blocks are in the middle layer and the position or color is wrong, they can be placed in the right front position first, and then rotated once in order to recover.
