1. The first step to restore the Rubik's Cube: Return to the bottom edge, select the white surface as the bottom surface, and cross the bottom of the Rubik's Cube. Trimming is to put a cross on each face. When you spell the cross, you don't rely on the surface, but on the layer. Go back to the first floor, that is, put a cross on the first side. This is very simple, but the spelled cross must be correct, that is, the colors of the four sides of the cross must be the same as the colors of the front, back, left and right center blocks.

2. The second step of restoring the Rubik's cube: return to the bottom corner, that is, restore the four corner blocks of the first layer of the Rubik's cube.

3. The third step of restoring the Rubik's cube: the second Rubik's cube is restored to its original position, which is the step of restoring the four Rubik's cubes in the middle layer.

4. The fourth step of restoring the Rubik's Cube: the position of the top edge. When doing this step, it depends on what the Rubik's cube is, such as "point": after completing this action step, it is a "small turn", so before doing this step, it is necessary to adjust the top layer to the right direction, and so on until the fourth step is completed, and the top layer yellow is restored to a cross cube.

5. Restore the Rubik's Cube Step 5: Vertex position Adjust all the top surfaces of the four vertices of the Rubik's Cube to the top surface.

6. The sixth step of restoring the Rubik's cube: put the top edge back, so that the color of the other side of the four top edges of the Rubik's cube that has been positioned is the same as the color of the other four faces. The order of the four corners of the Rubik's cube is completed in step 6.

7. Restore the Rubik's Cube Step 7: Return to the top corners, that is, the other two faces of the four top corners of the Rubik's Cube that have been positioned are the same color as the corresponding faces.
