It took nearly 20 minutes for Xu Jianren to untie his hand, and the students really had nothing to say in the end, so they each played with their mobile phones under the table.

"Is there a result?"

"Teacher, I've heard a different version of this story." Some students raised their hands to signal.

"There's more than one version, tell me which one you know." Xu Jianren put his hands in front of the stage and leaned forward slightly.

A classmate said: "The version I heard is from "Han Feizi Shuo Lin Shang", which mainly tells the story of a Lu couple who decided to move to live in the Wuyue area, but the neighbors thought that it would be difficult for them to make ends meet, because the locals wore neither shoes nor hats, and the skills mastered by the couple were completely useless. ”

"Oh, let me think."

Xu Jianren thought for a while, and then said: "The original text is not it: Lu people are good at weaving, and his wife is good at weaving, and he wants to migrate to Yue." Or to say, 'The Son will be poor!' The Lu people said, 'What? He said: "The more you do, the more people walk; It is also the crown, and the more people are haired. With the strength of the son, swim in the country of use, and want to make infinite, how can you get it? 'Lu people should not, take their wives with them. In March, I quietly returned. ”

"Seems to be." The classmate who asked the question was frightened by the ancient text blurted out, lowered his head and roughly translated it, and nodded his head again and again.

"This story included by Han Feizi should be regarded as the earliest in history, and there are two versions of the Lu people's migration, which are similar to the content of our shoes."

Xu Jianren took this opportunity to popularize additional knowledge for everyone.

"Have any of you ever heard the story of losing your shoes on the train? It tells the story of an old man who accidentally lost one shoe during his travels and simply threw the only remaining shoe out the window. ”

"When the shopkeeper asked him why, he smiled and said, 'Since the shoes are no longer available, it is better to throw them out and see if they can be fulfilled than to keep the remaining one.' ”

"I've heard it, it's Mahatma Gandhi."

"No, no, no, the version I've heard is George Bernard Shaw."

The classmates talked about it, some of them were Mark Twain, some were Gorky's, and some of them even omitted their names.

Not to mention why celebrities always like to do the same thing, how shoes that should have been on the floor fell out of the car window eerily are obviously not explained by ordinary reasons.

Xu Jianren suppressed the noise in the classroom and said slowly: "Most of the celebrity allusions we usually come into contact with have been artistically processed, and some are even simply made up, in order to instill a kind of ideological spirit in us. ”

"I can easily cite two hands from Newton who was smashed with an apple, Albert Einstein who scored 1 on a math test, Edison, the inventor, and an islander who likes to drink toilet water."

"We usually face a similar dilemma when we do data research or use existing data for analysis and modeling, how to draw an accurate and objective conclusion.

"The assumption is that the data is objective, but the person providing the data has a subjective position, which leads to a potential non-objectivity of the data, which doesn't sound like Schrödinger's data."

"It is also true that the same data, based on this hypothetical premise, is correct, but it is a fallacy to rest on another hypothetical premise."

"Let's take an example to make it easier for you to understand, there is an Internet organization that calculates the proportion of singles in each city through the annual theater movie ticket tie rate, is this reasonable?"

"It's obviously unreasonable, going to the movies is not necessarily with the object, and sometimes I will form a group with my roommates and girlfriends."

The girls in the front row near the podium reacted quickly, and it was not easy to pick up a question in Xu Jianren's class to send a score, so she had to seize the opportunity to brush up on her presence.

Xu Jianren said: "Yes, I think everyone can feel the same way, the single rate calculated based on this data will undoubtedly be biased, and then discuss further, let's select a reference sample to improve the accuracy of the conclusion." ”

"Double occupancy rate in rooms for each holiday." The first few familiar old drivers in the corner said quietly.

"Well, at first glance it sounds like a good choice, it's rare to be in the same room with the same sex, and if it were me, I would definitely meet up with my roommate at an Internet café, rather than going to the kind of place that makes people think about it." Xu Jianren's gaze continued to look around, expecting another answer.

"Tracking the number of holiday orders from male online shoppers." A polite white-faced student said.

"The collection and classification of data is a big project, and those who like to challenge the limits of human body function may wish to give it a try." Xu Jianren grinned.

"Check it out in the electronic archive." A fat man muttered.

Xu Jianren deeply agreed: "This is a lazy method that a genius came up with, it seems that the students don't have a deep understanding of the electronic archive, and they are interested in going back and studying it well." ”

Seeing that the topic was getting farther and farther, no one cared about the African salesman assigned before class, and the students couldn't bear to interrupt Xu Jianren's teaching progress and let him run wild.

This guy is a divergent type.,Habitually talking about somewhere, he suddenly thinks of something interesting and goes crazy to open a small stove outside of class.,Just dig a hole and don't fill it.,Force curious classmates to check the information after class.。

Wang Xu muttered: "Chinese people attach importance to the concept of family, but taboo death, the Western concept of family is indifferent, but in the face of death calmly, we must try to break this inherent connection, reconstruct a new logical chain." ”

"Not exactly." Chen Bo glanced at the time, and there were still a few minutes left before the class ended.

"The overall trend is."

"I have to explain something, for the cooking assessment in the evening, I have to ask Yao Wencheng to help me make beef brisket and radish."

Chen Bo couldn't find a suitable candidate for a while, and it was convenient to send a business order directly in the substitute group, but the father of the gold owner was also in the group, and if it was mistaken for a left-handed person who was eating the price difference, it would have a bad impact.

Yao Wencheng's level Chen Bo knows, he belongs to the jack in the spare tire, and he doesn't expect him to get a high score, just pass it.

"Hey, Brother Cheng, it's me, there's something to do at night, please leave the assessment to you."

"Brother Bo, what's the matter? It can be more important than the exam. ”

Chen Bo thought about it, what reason to prevaricate, only to see Wang Xu raise his hand and signal him to bring the mobile phone, Chen Bo hesitated for a moment and obediently did so.

"I'm his roommate, and we're going abroad in the evening."

"Going abroad? Awesome. Yao Wencheng sincerely admired.

"The business of dealing with Europeans and Americans, a billion yuan."

"Yes, the keyboard application profession is different, with an export of more than 100 million, and it is said so calmly."

"You have to deal with the dead, and the stakes are high."

"You guys are going to..." Yao Wencheng was stunned, obviously frightened.

Wang Xu then flickered: "Building a bridge between the living and the dead, isn't there a common saying, a community with a shared future for mankind, its scope is far larger than you imagine." ”

"I see, such a great cause, I am honored to participate in it and contribute a small contribution, don't worry, the task of assessment will be handed over to me, what kind of dishes does Brother Bo cook at night?"

"Hey, what are you cooking?" Wang Xu put down his phone and asked.

"Brisket radish." Chen Bo held back a smile and said.
