I often say that reasoning should be rigorous as science, that it should be ruthless, that it should not be blinded by emotion, otherwise it is possible to distort the facts to conform to the theory, rather than to derive the theory from the facts. - Sherlock Holmes: Basic Deduction

———————————————————————————

Yan Yitong's question is very nonsensical, it is even more excessive than embarrassing others with a question of the level of "impossible puzzle", after all, Cheng Mo doesn't know anything about her, let alone Cheng Mo, even Du Leng, who is quite familiar with Yan Yitong, doesn't know Yan Yitong at all.

What's more, even if people who know each other a little bit and guess out of thin air without clues, it is unlikely that they will guess, and they can only try their luck.

When Yan Yitong asked this question, everyone thought she was making things difficult for her.

But when Cheng Xiao heard that it was a music problem, he felt that he could try to guess it, so he asked curiously, "What is the hint?"

Yan Yitong, who was holding Cheng Mo's arm, said with a smile: "The hint is me! Guess mine, not other people's ....."

Silly white and sweet Cheng Xiao once again showed a confused expression, but it makes people feel funny when others make this expression, but Cheng Xiao makes this expression feel cute and good-looking, it is really beautiful - cute as if rubbing her face, in this era when beauty is justice, Cheng Xiao is undoubtedly the most righteous justice.

Although Xie Minyun felt that Yan Yitong was a little excessive, she didn't plan to speak for Cheng Mo, but just watched with interest how Cheng Mo would behave, and Du Leng naturally couldn't be unhappy with Yan Yitong because of Cheng Mo, so she just smiled and kept silent.

However, Cheng Mo didn't look at Yan Yitong but said very calmly: "You tell the answer first.... The young lady on the left..... "The young lady on the left he said was naturally Cheng Xiao who he didn't know.

Cheng Xiao was called Little Sister, and suddenly she was happy, as for why she was happy, just because the title of Little Sister made her feel very cute, the silly white and sweet girl was so good, it was easy to be happy, and the people who called her Little Sister didn't know her, and her eyes were very normal when she looked at her, which made her feel a little relaxed, unlike others who always looked at her with color, jealousy, greed, desire, worship, and desire.....

But the little boy in front of him, who didn't look amazing, looked at her through the lens and his eyes were very clear, clear and without any impurities, like a drop of water when an ice ridge melted under the winter sun.

This made Cheng Xiao's favor for Cheng Mo double, so he smiled and said, "Okay! I'll be the referee.....

Cheng Mo was afraid that he couldn't dream of it, so he just shouted: "Little sister." I gained Cheng Xiao's favor, and said again: "Thank you!" The reason why Cheng Xiao was chosen was because Cheng Xiao had judged that Cheng Xiao was the most heartless honest girl, although her profession was idol, but her eyes and smile were innocent that were not polluted by the world and the entertainment industry.

Cheng Xiao nodded and leaned over to Yan Yitong, Yan Yitong leaned towards Cheng Xiao's ear, and at the same time turned his head to stare at Cheng Mo, afraid that he would eavesdrop or peek at her mouth, and raised his hand to cover his mouth, muttering in Cheng Xiao's ear like a mosquito......

After saying that, he asked a little louder, "Did you hear clearly?"

Cheng Xiao nodded with some confusion and said, "I heard it clearly, but..."

Yan Yitong immediately put his finger to his mouth, compared a silent movement, and when he saw Cheng Xiao swallowing the words, he turned his head to look at Cheng Mo with some smugness and said, "OK, you can tell your answer.....

Cheng Mo didn't even look at Yan Yitong and said directly: "Vaporwave-vaporwave...."

Before Yan Yitong could speak, Cheng Xiao looked at Cheng Mo in disbelief and said, "My God, can you guess this?" or did you already know that it was amazing...."

Du Leng saw that Cheng Mo answered the answer without hesitation, and frowned slightly, if it weren't for Cheng Mo's lack of interest and no threat, he must have suspected that Yan Yitong was deliberately trying to make trouble.

Xie Minyun was also very surprised that Cheng Mo could find the answer so quickly, such a performance was almost mysterious, and the legendary fortune teller had a fight, she guessed that Yan Yitong must have revealed some information, otherwise Cheng Mo would not have hesitated, just because she didn't know much about the music form of "vaporwave", so she didn't know.

Yan Yitong was not as surprised as Cheng Xiao, the corners of her mouth curved a beautiful arc, although Cheng Mo found the answer in an instant to her surprise, but this was indeed the surprise she expected, she let go of her hand and grabbed Cheng Mo's hand and said, "Give me the phone, I'll transfer it to you....."

And Cheng Xiao still said with a blank face: "You.... How do you know? You can't have guessed because I said a word, can you? Is it my leaked information?"

Cheng Mo shook his head and said, "The information revealed by the young lady is not very critical, of course your words did make me affirm my answer...."

Cheng Xiao still said with a blank face: "What do you mean?"

Cheng Mo said: "Actually, I thought at the beginning, I must say sorry to my classmates here, it is my habit to observe people, and this must be said to be deductive..... At the beginning, I saw her wearing retro glasses, which seemed to me to be a bit outdated and excessive, and this kind of obsolescence contradicted her dress, because her clothes belonged to the more trendy cyberpunk style in the eyes of people like me, who are not sensitive to fashion..... Looking at her socks pink and gray checkered, one of the favorite colors used in vaporwave music....... Not only that, but the blue dolphin on her head is also one of the most popular elements of Vaporwave, and as for the rough slightly explosive hairstyle and the fierce clash of the whole outfit, all of this points to the fact that this student loves Vaporwave music....."

Then Cheng Mo took out his mobile phone without shame, opened it and entered the school APP, clicked on the QR code, signaled her to transfer to another school, and then looked at Cheng Xiao and said: "Vaporwave music promotes nostalgia for retro culture, nostalgic artifacts and mass production, and of course, the technology of consumer capitalism and pop culture, and the criticism and satire of hippie culture in the 80s of the last century - and your surprise is because the music that this classmate said is really very niche, and the niche doesn't even know you....."

"But it's too normal for an idol singer to not know niche music like vaporwave that doesn't even have lyrics....."

Cheng Mo is very easy to say, in fact, using the deductive method to speculate on a person is something that requires a lot of practice, a pair of keen eyes must be exercised to come out, not that you can do it if you master the objective laws, like calculating the bust circumference.......

Cheng Mo started practicing professional reasoning, this is his little game, everyone on the street is a level, the difficulty is different, the problem is that you don't know which person is easy to reason, and this point needs to be observed more to accumulate experience.

For example, when Cheng Mo was at the airport, a person came in front of him, with big words written on his back: so-and-so company, there is no need to ask, generally wearing company clothes and school uniforms and some work clothes, it is recommended not to reason about the profession.

This is a normal person, it can't be called reasoning, and if you are facing a very ordinary person, you need to use your brain, if you are facing a spy or an agent, it is better to give up - you can't find anything!

A person's occupation is related to his education level and status class, and this can be easily seen from the clothing, generally men wear suits, women wear clothes similar to work, and it is very formal, it should be easy to see.

Therefore, looking at a person first from the clothing, some people say that it is easy to judge people by their appearance, but the reasoning is to judge people by their appearance to a certain extent, because they must first have a framework for him before they can fill in other information.....

Of course, Cheng Mo will not say these things.

Yan Yitong transferred a thousand learning points to Cheng Mo, and naturally knew that Cheng Mo's ID was called - Running Fat Man.
