The following is written by myself, and the photos can't be displayed. I hope it helps you.
Fourth, the spelling of the yellow face (the yellow center face is the top face):
This step is more troublesome. When you meet a graphic, look at the placement method of the graphic first, and then follow the formula, so it won't be so messy.
After the second layer is put together, the surface with yellow center point will appear the following conditions:
Look at the colors of the top four edges and the center point first (* * * 5):
1. If one of the five blocks is yellow, it must be the middle block (as shown in figure 12). It doesn't matter how the four sides are placed:
G: Shun Shun → Right Shun → Up Shun → Right Inverse → Up Inverse → Forward Inverse.
After rotation, a "┏" shape will appear on the top floor (as shown in figure 13). Please refer to step 2.
2. If three of the five pieces are yellow, a ┏ or ━ ━ will appear after turning the whole Rubik's Cube (as shown in figure 14).
When these two situations happen, just place the Rubik's cube as shown in the figure, repeat the G formula, and two, three or four non-yellow faces will appear, and then press 3, 4 and 5 steps according to the shape you turn out.
3. When there are three non-yellow faces on the top surface, there are two possibilities. Because it looks like a small fish, it is named "Xiaoyu ①" (as shown in figure 15) and "Xiaoyu ②" (as shown in figure 16). Adjust the cube. The yellow corner on the top is located on your left rear (the fish head is this corner). Place the Rubik's Cube as shown and rotate it as follows:
Fish ①: right inverse → top inverse → right cis → top inverse → right inverse → top 180→ right inverse.
Fish ②: Shun Shun → Ding Shun → Shun Inverse → Ding Shun → Shun Shun → Ding 180→ Right Shun.
Press which formula you want to go to, and then go.
Turning to steps 4 and 5, there is a formula of "two turns and four lefts": "two, four" means that the top surface has two or four surfaces that are not yellow; "Back, left" means that the yellow in the upper left corner is facing back or left. (Adjust the top floor so that the corner block that is not yellow is located at your left rear) Do you feel a little confused, then you should see it clearly below!
4. When the top surface has two surfaces that are not yellow (these two surfaces have two different positions). Make one of the two corner blocks where these two faces are located at your left rear, turn the yellow face of this corner block backward (as shown in Figure 17), and then rotate according to the formula of "fish ①". After the turn, you will find that it has become a pattern of "fish ②" again, and then turn it according to the formula of "fish ②". (Pay attention to the placement of the Rubik's Cube)
5. When there are four non-yellow faces on the top floor (the square where these four faces are located must be four corner blocks). Turn one of these four faces to the left rear of the top floor, so that the yellow face of this corner is left (as shown in figure 18), and then turn it according to the formula of "fish ①". Turn the pattern of "Fish ①" and turn it again.
So the yellow-faced woman is getting better! ! !

5. After turning the top yellow surface better, the following two situations will occur:
1. Of the four sides, only the top two corner blocks on one side have the same color (sometimes the top three blocks on this side have the same color). Let this face face your right, put the spelled yellow face forward (as shown in figure 19), and then rotate according to the following formula:
H: Right 180→ Bottom 180→ Right Inverse → Top Inverse → Right Shun → Bottom 180→ Right Inverse → Top Shun → Right Inverse.
2. Among the four sides, the colors of the two corner blocks at the top of each side are different. Now, just put the yellow side forward (it doesn't matter which direction the four sides are facing). Then press formula h to turn, and the first situation will appear after turning, and then press the first turn.
In this way, among the four sides, the top two corner blocks on each side are the same color as the two layers below.
Six, after turning four corners, there are two situations, as follows:
1. The colors of the top four corners are different from those of its adjacent corners (as shown in Figure 20). The yellow surface is the top surface, and the directions of the four sides don't matter. Rotate according to the formula of "Fish ①", then rotate the whole Rubik's Cube horizontally by 180 to form the pattern of "Fish ②", and then rotate according to the formula of "Fish ②", and the shape of the second case will appear. (Or press the formula of "fish ②" first, and then press the formula of "fish ①")
2. One of the top four blocks has a block with the same color as its neighboring block (as shown in Figure 2 1). Now, one of the four sides is completely spliced, so you should face this side to your right, or use the yellow side as the top surface. Then according to the formulas of "Fish ②" and "Fish ①", a miracle will appear. (Sometimes it is successful to turn once, and sometimes it needs to be turned twice, because there are two situations here: look carefully, the three sides will return to their original positions clockwise or counterclockwise. )
If you are interested, please read the following passage, which will enable you to quickly restore the Rubik's Cube in the second step of the sixth step. If these three sides are restored clockwise, just rotate them in step 1 of the sixth step (fish ② first, then fish ①); If you restore these three pieces counterclockwise, put the yellow side up, put the Rubik's cube on the front of the spliced side, and then rotate according to the steps of "Fish ①" and "Fish ②", the Rubik's cube will be restored after only one turn!
