Step 1: Of course, if you want to own a Rubik's cube, go to the supermarket and buy a Rubik's cube (it is recommended to buy at least a better one), and then remember what color each face is. This is very important. For example, I like to use blue as the background, and the annotations are: bottom blue, front green, back orange, left yellow and right white.
Step 2: Disrupt the Rubik's Cube, don't be afraid! You can destroy it in any way. You have to believe in yourself. It's actually quite simple.
Step 3: We really should get started. First, choose a color at the bottom (white is recommended) (The Rubik's Cube has six sides, so you can choose whatever you want. If you choose the color at the bottom, the color at the top will be decided. As mentioned in the note above, the colors are corresponding).
Then we can see that there are three layers between the bottom surface and the top surface, which are called the first layer, the second layer and the third layer from bottom to top respectively. Alas, it feels like nonsense, but I'll know it's necessary later. Anyway, I choose white as the background now.
First, find the face whose middle piece is white. Then, put a cross on this face in the color order you remember. Remember: the color should be correct. This step does not discuss the formula, play by yourself!
Step 4: Align the other four corner blocks at the bottom of the cross.
