Return to 1983 and be a detective

In the independent small building of Longshui Criminal Investigation Brigade, Xu Shan was playing chess with Liang Feng when he suddenly heard a knock on the door.

He said "Come in" and Su Jing came in.

She smiled: "Master Xu, you are really bad."

Liang Feng couldn't help but look sideways at these words. If he hadn't known about the relationship between Xu Shan and Su Jing, he couldn't help but wonder when these two guys had an affair.

Xu Shan also felt goosebumps all over his body when he heard this: "You have something to say, you'd better say it clearly."

"Are you selling movie tickets and towels?"

"Yeah, isn't this something everyone knows?"

"Did you tell everyone to collect towels and send bicycles?"

"It's not a secret. Let's talk about it in every game."

"Are you investing different towels in each area? You can only collect at most three types of towels in one area?"

When Su Jing asked, Xu Shan knew what she wanted to say: "That's right, so what?"

"Then is your behavior opportunistic and deceiving customers?"

The two words that bother Xu Shan the most are rebirth and speculation.

He just wants to say something now, woman, you have touched my reverse scales.

But he also knew that Su Jing just didn't have a brain and did it unintentionally.

"This can't be called speculation, let alone deceiving customers, because our prizes can be collected. For example, if a customer watches a movie in Xiyang area and another movie in Jinwu area, he can collect them all. Four towels, is this hard to do?”

In fact, this would not be difficult at all in later generations. From Xiyang to Jinwu, the high-speed rail only takes half an hour. From Xiyang to Linzhou, the high-speed rail takes a little more than an hour. However, it is now [-]. In this era, most people go A trip to the county town seemed like a trip to some extraordinary place, let alone traveling to two cities just to watch a movie.

When Su Jing and Zhang Chengan went to Jinwu to do business with Zhang Mingwu, they went to see a movie and got two plum blossom towels. She thought they were all plum blossom towels and originally planned to come back to mock Xu Shan and accuse him. Deceiving consumers, but the little fat man's towel collection action made her understand Xu Shan's marketing strategy.

I have to admire Xu Shan's strategy, which can maximize people's enthusiasm. Everyone now has some money in their pockets, but they are not willing to spend it.Because everyone is willing to deposit money in banks these days, and bank interest rates are really high.For any half-year fixed term, the interest rate is 5.00%. If it is fixed for five years, especially in the late 80s, the interest rate is around 15.00%, which is equivalent to having 100 million deposited in the bank for five years and then withdrawing it. By then, it was 170 million.What an astonishing amount this is.

One thing that can also be reflected from this is that the economic development in the 80s was so fast that taking off is not enough to describe it. It can only be said to be like riding on a rocket.

In Su Jing's view, this was deceiving consumers. She had no intention of suing Xu Shan. Although she and Xu Shan were still not very good at dealing with each other, after getting along for such a long time, Xu Shan's business ability also impressed her. Impressed, her mentality is also quietly changing.

She doesn't even object to Xu Shan being with Su Wan, but sometimes she hasn't completely changed her role yet and wants to find an opportunity to mock Xu Shan and see how speechless Xu Shan is.

However, Xu Shan taught her a lesson in return: "Comrade Xiao Su, this is your fault. We who are engaged in criminal investigation must not only replace ourselves as ordinary people, but also let ourselves jump out from time to time and look at problems from a higher dimension." . Take my marketing this time as an example. From the perspective of the people in Xiyang or Jinwu, you must have spent a lot of effort to get four towels together, but you stand in the entire Lin province. From a perspective? It’s actually very easy to put together, right?”

"But who would go to two places to watch the same movie?"

"This is not something I should consider. I am doing business, not charity. I propose rules. As long as the rules can be implemented, it does not count as deceiving consumers. All I can say is that the final right of interpretation belongs to the manufacturer. .”

Su Jing was rendered speechless by Xu Shan.

At this time, Liang Feng was inspired and asked Xu Shan: "You just said that criminal investigation should be carried out in a higher dimension. What does this mean? Can you explain it to me in detail?"

Seeing Liang Feng looking so serious, Xu Shan was a little surprised and asked him, "What don't you understand?"

Liang Feng scratched his head with one hand in embarrassment: "What is a dimension? How can I stand on it?"

Only then did Xu Shan understand that the amount of information people in this era receive is too limited. Even many people at the forefront of the industry in this era have much less information than the average person in later generations.

"Well, how about calling everyone together now and I'll tell you about dimensions and the like."

When Su Jing heard this, she was naturally very happy and hurriedly called for people. This kind of supplementary class is very common in the criminal investigation brigade now. Everyone is used to it, and everyone thinks that what Xu Shan talks about is all practical information. , are all theories that I have never heard of before.Therefore, everyone is like a dried sponge. When Xu Shan lectures, they will try their best to absorb the water of knowledge.

When everyone arrived, Xu Shan looked around and started talking about the topic of dimensions: "As for the definition of dimensions, I guess everyone actually has some vague concepts, but no one has summarized them. Just like saying that one-dimensional is a line, between one point and that point, a straight line or a curve, this is the concept of one-dimensional, while two-dimensional is a surface, and three-dimensional is a solid. The world we live in is also a three-dimensional space. , and the fourth dimension is the concept of time. In fact, there are five-dimensional, six-dimensional and other higher-dimensional worlds. However, we have never seen those worlds and cannot see them.

Why is it said that it cannot be seen? For example, a caterpillar can only move from one point to another, so we can treat it as a one-dimensional creature, while an ant can move on a plane, so we can treat it as a one-dimensional creature. It is a two-dimensional creature, a flea. Not only can it move on a flat surface, it can also jump up. So treat it as a three-dimensional creature.As for us humans, we have the concept of time, but we cannot see all of time. We can only be regarded as three-and-a-half-dimensional creatures.

For a caterpillar, it cannot understand the behavior of ants, ants cannot understand the behavior of fleas, and fleas cannot understand the behavior of us humans. "

At this point, Bao Laohei said in a playful manner: "Fleas don't need to understand us, they just need to understand that if they bite us, they will be full."

Everyone burst out laughing.

At the same time, everyone also understood the concept of dimensions. At this time, Liang Feng quickly urged Xu Shan and said, "Tell me how to see things from a higher dimension."

"Actually, it's very simple. Generally, when we think about problems, we all like to act on behalf of others. This is a good habit, but it is not good enough. It is said that the authorities are obsessed and the bystanders are clear. When considering a problem, you must jump in and out and look at the problem from different angles. For example, if a person stands on the ground, no matter how flat the ground is, you can only see things up to [-] kilometers away. But if you climb to a high place, Confucius climbed Dongshan and Xiaolu climbed Mount Tai. As for the small world, for example, after humans went to space, they saw what the earth looked like and took photos of the earth with satellites. This verified the theory of a round earth. However, there are still countless people who believe that the sky is round and the earth is round. Flat, because they always only stand on flat ground to see things. I give these examples to show that as long as you stand high enough, you can see farther things.

As for how to do it?Then you need to put yourself in the shoes of someone in a higher position and look at this issue from a more macro perspective.What I say is very abstract. It is best to come up with a case and let us solve it from two angles at the same time, so that everyone can experience what it means to look at the problem from a high dimension. "

In fact, this is entirely because Xu Shan found that he was running out of words and his knowledge reserve was not enough. If he continued to talk, his secret would be exposed.

But at this moment, He Dongyang walked in and said with a heavy face: "Everyone, please interrupt, there is a new case."
