1. Pull out a cross at will.

2. Front right homing (up ← right ↑ up → right ↓ up → positive and negative ← positive sequence) and front left homing (up → left ← left ↓ up → positive and negative sequence).

3. Top cross homing: lower right, upper left, front reverse, upper left and right front (1-4 times).

4. Top-level homing: lower left and right, lower right and upper right (2 or 4 times), lower right and lower left and upper right (2 or 4 times).

5. Vertex homing: 180 right, lower back, upper right and forward, 180 right, 180 right.

6. Top recovery: upper right, upper right, upper left, upper right, upper left, upper right, upper left, upper left, upper right, upper right 180.

Now the Rubik's cube is divided into two-order Rubik's cube, three-order Rubik's cube, four-order Rubik's cube, five-order Rubik's cube and so on. But the basic method of restoring the Rubik's Cube is the same, layer by layer. Many beginners of Rubik's Cube hope to recover one side at a time, but this way of thinking is completely wrong.

Without such layers of spatial imagination, it is difficult to completely restore the Rubik's cube. In addition, the most important thing to restore the Rubik's Cube is to remember the formula and use it reasonably after memorizing it. It's like when you do a math problem, you must first understand the formulas and theorems in the book, and then use the formulas to solve the problem.
