PS: Thank you for the many tips from the Emperor and the Queen of Earth, the Dragon of the Heart, and the First Housemaid in Jiangnan, the monthly pass for Mercury One, and the highly praised vote of SOI! It's a little bit more going on today, sorry!

The return of the monkey made the entire Chujiazhai happy. Everyone was even more excited about the monkey wine that the guy brought out, and even the old guys in the research institute began to bewitch the monkeys, and next time they got more of them. After all, it's a legendary thing, not something that can be drunk with money, no matter whether the taste is as good as the legend says, everyone has already regarded it as a boutique, no matter how you say that this world is still scarce and expensive.

After these turmoil, Chujiazhai returned to its original trajectory again, simple but fulfilling. It was only not long before a small tourist brought a Rubik's cube that the children of Chujiazhai became restless again.

Children are almost like this, and even people are like this, they don't know what they have, they know what they have, and they know what they love others.

The children in the city are very envious of the children in the countryside, who do not have so much homework, and can go down to the river to fish, go up to the mountains to play flowers and grass, like birds, and be free.

However, the children of Chujiazhai are also envious of the children from outside, playing with various advanced game consoles, wearing very beautiful clothes, and so on.

The Rubik's Cube seems to have magical power, constantly attracting the attention of many children in Chujiazhai. Nowadays, the children of Chujiazhai have a lot more money in their hands, and a Rubik's Cube is not very expensive. As a result, many interested children have one for each child. Although he couldn't play, he still took it around and saw that Chu Jiaqiang's egg was in pain.

There is actually a pattern to playing this, but those little guys don't know it, and they twist those blocks of different colors indiscriminately, but they can't twist a face of the same color.

"I mean, you little guys, are you going to do it? Spatial thinking is terrible! Chen Wu said.

The Rubik's Cube is a very test of spatial thinking, which was invented by a foreign professor just as a teaching tool to help students enhance their spatial thinking ability.

But. Keeping those small squares free to turn without falling apart is not only a mechanical problem, but also involves wooden shafts, seats, and tenons.

However, when the Rubik's Cube was in hand, after turning the Rubik's Cube a few times, I realized that how to restore the chaotic color blocks was actually an interesting and difficult problem. As a result, it became popular all over the world shortly after its creation, and people discovered that this small cube was really mysterious.

This toy is similar to the "Huarong Dao" invented by the Chinese. The invention of the French "Independence Diamond" piece has been called one of the three incredible minds of the world of intellectual games. And the popularity of the Rubik's Cube is a miracle in the world of intellectual games.

"There's a formula for playing this, but it's a pity that you can't understand it." Li Quan had also played with this thing before, and he was confused at first, but after being pointed out, he found out that the so-called intellectual toys were actually a little mentally retarded. The Rubik's Cube can be restored back according to the formula. And even if you don't use formulas, there are even more stupid ways to do it, just memorize some formulas.

"If you play according to the formula, it's really not challenging." Chu Jiaqiang said with a smile. When I was a child, I thought this thing was quite magical, and I played with others for two days until college. Completely lost interest.

But having said that, without formulas and formulas, it is really not easy to study a person's spatial thinking. At least at the time, he could only sort out one face.

"Teach me quickly." When those little guys heard how simple these people were talking about the Rubik's Cube, they were immediately moved.

In their opinion, the people who can play this imitation are quite face-saving. I've seen this toy on TV before. Therefore, the impression on the child is particularly mysterious.

Chen Wu immediately put on a stand and hugged his sleeves. Then point to a child's Rubik's cube and ask someone to serve it. The little guy was also very cooperative, and sent the Rubik's Cube up with both hands.

"Look, listen carefully one by one, and I'll show you a demonstration." Chen Wu grabbed the third-order Rubik's Cube, which was a kind of Rubik's Cube that was relatively easy to play.

In addition to the third-order ones, there is a simpler one, with only four squares on one side, also known as the pocket Rubik's Cube, mini Rubik's Cube, small Rubik's Cube, and Ice Cube Cube, which is a cube structure of 2×2×2.

In addition, there are fourth, fifth, and even more, and the more orders, the more complex they become. Finally, it is more rare to have a special-shaped Rubik's Cube, a mutant Rubik's Cube, a mirror Rubik's Cube, and so on.

When the little ones heard this, they all immediately quieted down, and one by one they became good babies, much more attentive than listening to the lecture in the classroom. They just like that, they don't want to learn the content of the class, they just like these sideways.

"Tsk! If you are so serious in class, you will get a full score in the test. Zhou Furong joked.

"Don't make a noise!" Chen Wu glared at Zhou Furong, the atmosphere he had finally created was ruined by this guy, and he naturally had no good anger towards Zhou Furong.

Zhou Furong rolled his eyes, feeling that this pretending guy was quite speechless.

"The first step is simple, to twist out the bottom cross. When making a cross, keep in mind the four colors, and make an impression of the corresponding color changes on both sides. It is necessary to be able to remember the color of one side while remembering the color of the other side. Chen Wu explained and demonstrated to everyone, quite a teacher.

The first step was indeed not difficult, and soon the little ones learned it, and one by one they were happier than picking up the money. One of the little boys even shouted, "I've learned!" It turned out to be that simple. ”

Chu Jiaqiang and the others almost burst out laughing. This is the first step, and it is far from a complete restoration. Later, they won't dare to say it's simple! Although there are formulas and formulas, they are not so easy to remember.

"Don't be complacent, this is the first step, and there is still a long way to go to success." Chen Junzuo said to the children solemnly.

Then the whole bottom surface is sorted out into the same color, this step is not difficult, Chen Wu just did one side, and a little guy comprehended.

"This little guy is good! So quickly see clearly. Tang Liye praised. Actually, he doesn't know how to play with this thing, so he's trying to watch it himself, but he still can't turn it around in his head. Of course, he wouldn't say anything that hurt his face, at least not in front of his children.

Then, it's time to complete the first two layers. This step is a bit complicated, the little guys are dazed one by one, and they know that the whole army is wiped out at a glance.

Chen Wu had to get them two more times, but no one remembered it clearly. Finally, he said the mantra of this step so that the children could memorize it. This time, the children were not lazy, and some even took notes and prepared to take them back to memorize. In the evening, the parents were all happy to see that the children were so active, but they didn't know that the little guy was not learning.

The next step was to restore the top surface, and under the eyes of everyone looking at him seriously, Chen Wu suddenly touched his head in embarrassment and smiled: "This, that, I forgot the last step, you can figure it out in the old village." ”

As soon as these words came out, everyone was stunned, and then burst into laughter.
