The first interviewer was eliminated, and after the person left, everyone didn't rush to call the second interviewer, Yan Xiaoqin hurriedly asked, "What the hell are you doing?"

Chen Qiaoshan said: "It's nothing, haven't you all seen it, she was stumped by a simple question, that's all!"

Yan Xiaoqin glanced at him and threatened, "Do you want to say it?"

Chen Qiaoshan didn't go around in circles anymore, the two of them had just pierced the last layer of window paper, and now it was the time to eat the marrow and know the taste, he didn't want to make trouble for himself.

"To put it bluntly, it's actually worthless, finance has a 72 rule, which can easily calculate the time for investment doubling or halving, which is a trick, whether it is stock speculation or investment, it is often used, of course, this is not accurate. ”

Chen Qiaoshan explained a few words briefly, and the few people present were not stupid, and they immediately understood.

Wang Lin questioned: "No, your answer has zero and integer, and it is not divided by seven or two?"

Chen Qiaoshan smiled and continued: "To deal with general problems, the rule of seventy-two is more than enough, actuarial science, the middle also needs to correct the variable according to the size of the interest rate, in fact, the reason is very simple, you list an equation and expand it with the Taylor formula, you will find that 0.72 is just a valuation, and the error is still relatively large......"

Wang Lin asked again: "Since there is something closer than 0.72, why is it called the rule of seventy-two?"

"Because of convenience, from one to nine, only five and seven are not divisible by seven two......"

A few words were perfunctory by Chen Qiaoshan.

There are many similar gadgets in the financial field, all of which are the accumulation of experience, and simplifying the complex is also a practical need.

The interview continued, and I met three more in a row, and it can be seen that all of them are shrewd people, who can speak, write, and calculate, but Chen Qiaoshan is not very satisfied.

After thinking about it secretly, he suddenly realized that he might have done something wrong this time.

Complicated likes to make friends with simple people, and the assistant follows him all the year round, Chen Qiaoshan is subconsciously quite picky about this candidate.

No way, he hides too many secrets, he can't be trusted, and it's hard to walk into him.

Looking back on the experience of more than a year, unless Chen Qiaoshan is willing, it is difficult for outsiders to approach, in the past year, I have dealt with the three religions and nine streams, and I know a lot of people, but there are not many real friends.

Chen Qiaoshan sighed secretly, the crux of the problem turned out to be here, but it couldn't be solved if it was in his throat, and just as he was thinking, the last interviewer also entered the conference room.

Chen Qiaoshan took a look, and he actually knew the person who came, it was Tuo Xiaoxue, a fellow countryman from Peking University Xinke.

The two are actually not very acquainted, and they have met three times after a full fight, but they have a deep impression of each other.

Tuo Xiaoxue naturally noticed the existence of Chen Qiaoshan, she was only a little surprised, and before she could bother to say hello, she introduced herself at Liu Chang's request.

"Hello everyone, I am very fortunate to participate in this interview, my name is Liu Chang, and I am a junior majoring in microelectronics at Peking University......"

Chen Qiaoshan flipped through his resume, but he didn't expect Tuo Xiaoxue to choose an unpopular major, of course, this is also relative.

Nowadays, a swarm of people who learn computers are running to CS, and it is difficult to recruit electronics and microelectronics majors, especially those who choose majors by entering the school, and the CS and microelectronics majors of Peking University Information Science and Technology have had an embarrassing situation of 10:1 enrollment.

Tuo Xiaoxue's interview was decent, not good, not bad, after all, he is the champion in Nanyang, and his IQ is definitely online.

After asking the usual questions, Liu Chang glanced at Chen Qiaoshan, it was really troublesome to find an assistant for this one, except for the first one, he had never interfered, and he didn't know what it meant.

The interview was about to end, and Liu Chang gave him an inquiring glance.

Chen Qiaoshan remembered last year's incident, how to say that it was an old acquaintance, and after a little pondering, he said: "Wang Lin, give her a piece of paper and pen!"

Again! The conference room fell silent.

Tuo Xiaoxue didn't know why, she glanced at Chen Qiaoshan, a little strange in her heart, and then looked at the interviewer, several people had a smile on their faces, she was very puzzled, and it was hard to say anything at this moment.

Seeing that Tuo Xiaoxue took the pen and paper, Chen Qiaoshan said: "Last question, you are a microelectronics major at Peking University, you should have designed an analog circuit layout, right?"

Tuo Xiaoxue nodded, "Yes, analog electronic technology is the foundation of electronic circuits, and it is a compulsory course." ”

Chen Qiaoshan said: "Okay, I think this question should be difficult for you." ”

Without waiting for the crowd to react, he continued: "My problem is very simple, don't think about insulation, matching, layout, equalization and coverage, you can help me draw a square circle on the paper!"

A square circle?

Before the joker was born, this question was enough to make people collapse.

Tuo Xiaoxue was stunned, does this have anything to do with the circuit diagram?

noticed that the women on the other side all wanted to laugh and forced themselves to hold back, she was not stupid, and naturally knew that she was being troubled.

Tuo Xiaoxue had long forgotten the grudge between the two, but at this moment, the old grudge was not over and a new grudge was added, and she couldn't wait to tear Chen Qiaoshan apart.

Although she was angry, Tuo Xiaoxue was unwilling to give up, and her mind was still desperately analyzing how to draw the square circle.

She knows about circumcision, which is to calculate pi and constantly multiply the number of sides of the circle with regular polygons, but what does this have to do with squares?

Besides, talking about analog circuit diagrams, which square circle to draw?

The more Tuo Xiaoxue thought about it, the more confused her brain became, and after thinking about it for a while, she didn't have a clue at all, she couldn't help but be very annoyed, she had a part-time job, and she was so disturbed by Chen Qiaoshan.

Tuo Xiaoxue also has a temper, threw the pen on the table with a "snap", pointed at Chen Qiaoshan's nose and said: "Chen Qiaoshan, I have a grudge against you or what, why can't you get along with me everywhere?"

was called out on the spot, several people present were very curious, and they were acquaintances for a long time, Yan Xiaoqin stared at Chen Qiaoshan and asked, "You know each other?"

There is nothing to hide, Chen Qiaoshan nodded and explained: "She is also from our Dengzhou, her parents are both high school, and she met twice in high school. ”

"Really?" Yan Xiaoqin's face was suspicious, "Why haven't I heard you say it before?"

"Why didn't you say it, Dr. Tuo in the health room is her father, and when he went to steal masks with Sun Fatzi, he met her. ”

Chen Qiaoshan lowered his voice and said a few words, Yan Xiaoqin thought about it, there is indeed such a thing, Sun Guangming made fun of it, thinking about the pranks of the two, she glanced at Chen Qiaoshan angrily.

Seeing that the two knew each other, Liu Chang didn't want to toss anymore, she said: "Mr. Chen, this is the last one, you have to make a statement, right?"

Chen Qiaoshan glanced at Tuo Xiaoxue and couldn't help laughing: "It seems that you can't draw a square circle, but it doesn't matter, you have been admitted." ”

The ending was unexpected, everyone inevitably muttered in their hearts, Chen Qiaoshan didn't care about anything else, and said directly: "Sister Chang, you help take it for two days first, let her familiarize herself with the environment first." ”

"Wait a minute. Seeing that Chen Qiaoshan wanted to slip away, Yan Xiaoqin hurriedly stopped him, and she asked, "You haven't said the answer yet!"

Chen Qiaoshan glanced back at everyone and asked, "You really want to know?"

Wang Lin smiled: "What is the sale, say it quickly!"

Chen Qiaoshan didn't say anything, picked up the pen, wrote a square circle on the paper, turned around and left, leaving only a few women standing on the spot with shocked faces.

……

August 8 is a very auspicious day for the Chinese people.

In a few days, the Athens Olympics will begin, and the countdown to the Yenching Olympics has begun.

The Chinese people have a very strong Olympic plot, especially the Olympic Games are about to be held at home, and the influence can only be described as overwhelming.

Since the morning, we have received information feedback one after another, and Internet people from Tiannan and Haibei have checked in at the Friendship Hotel and Resource Hotel.

At noon, Chen Qiaoshan received news that Elliot had completed an options transaction with Mitsui Bank.

Two million dollars in exchange for a purchase right contract, thinking about it carefully, Chen Qiaoshan couldn't help but be a little worried.

Money is the investment of real money, but there is not a barrel of crude oil.

Chen Qiaoshan only bought the right to buy oil, Mitsui Bank could not have oil, they were just passing on the risk, as for the Singapore branch of China Aviation Oil, crude oil must be there, but whether there is 1.1 million barrels in the inventory is unknown, which is one-thirtieth of OPEC's daily output.

To put it bluntly, this is a gambling contract, a typical capital speculation, $2 million will not enter the crude oil futures market at all, it is completely an air-to-air transaction, and this is how the bubble came about.

Chen Qiaoshan couldn't help but flash a thought, air-to-air is undoubtedly a shortcut to make money, and there is huge arbitrage space hidden behind it, especially at the moment, when domestic financial development is seriously lagging behind, and it is not too simple to get out of the way.

In an instant, he forced himself to hold it again.

Chen Qiaoshan was secretly frightened, the interests are really forgetful, think about the scams of spot silver, oil, and precious metals in later generations, the funds involved are all starting from 100 million yuan, and some projects are even endorsed by the government, and the so-called financial innovation is often a financial trap, which makes people shudder to think about it.

Chen Qiaoshan shook his head, some money can't be earned, of course, he doesn't lack ways to make money, thinking of this, he is sure in his heart, after this battle, I'm afraid he doesn't have to worry about financing anymore.

……

Chen Qiaoshan looked at the financing application, the door of the office was knocked open, and Tuo Xiaoxue walked in cautiously, "Mr. Chen, the stationmaster of the laggard will come over immediately, Mr. Liu asked me to ask, is it convenient for you to meet?"

Seeing her questioning expression, Chen Qiaoshan didn't care, she obviously hadn't gotten used to it yet, and it wasn't surprising that in the past year, her changes were too great.

Dong Qifeng should be in the conference affairs group at this time, he is the boss of the laggards, he is familiar with many stationmasters, and he can be said to be the leader of the stationmaster circle, and he should be in charge of reception, there should be no problem.

Chen Qiaoshan ignored her careful thoughts, and he asked, "What is Dong Qifeng doing here?"

Tuo Xiaoxue hurriedly stopped her messy thoughts, and said, "Mr. Liu said that it was to discuss the evening exchange meeting. ”

"Okay, I know, when he arrives, you ask him to come over. ”

Tuo Xiaoxue responded, turned around and walked out of the office, she shook her head, when school started last year, this guy couldn't even afford a mobile phone, and he was laughed at by his roommate, but now, he has become Kangsheng's boss, and the circumstances of his life are really strange.

Chen Qiaoshan didn't have the heart to think about it, he had already gone through the stack of financing applications in his hand twice, and there were very few impressions in his memory.

He is not surprised, Zhongguancun is a distribution center for entrepreneurs, 200,000 yard farmers gathered here, creating an annual output value of 70 billion, but there are only a few successful cases.

The reason why Dai Zhikang has become a benchmark for post-80s IT migrant workers is precisely because he can start from scratch and create a successful product by himself, which is an inspirational example.

Not long after, Dong Qifeng entered Chen Qiaoshan's office.

"Mr. Chen. Dong Qifeng said hello with some restraint, although the boss in front of him was very young, he didn't dare to take it lightly.

The stationmaster meeting is his long-term wish, in the past, the laggards could only engage in a small range, this kind of national gathering, is simply a luxury, just the rental of the venue, it is not something Dong Qifeng can afford, not to mention free accommodation and 300,000 sponsorship, as well as financing platforms, Internet celebrities on-site exchanges......

"You're welcome, please be seated. ”

For Dong Qifeng, Chen Qiaoshan still values it very much.

Although it has been difficult for laggards to achieve profitability, it is one of the three major webmaster stations in China, and it is the best choice for small and medium-sized websites to do external links, and its influence has always been high.

Chen Qiaoshan has a bottom line in his heart, and those who engage in technology are the most worthy of respect.

Dong Qifeng asked, "Mr. Chen, are you present at tonight's exchange meeting?"

"I'm not showing up. Chen Qiaoshan didn't hesitate, and directly refused, "It's good that you, Mr. Dai and Lao Wang come forward, they are all from technical backgrounds, and you have a common language on this occasion." ”

Dong Qifeng was a little disappointed, although the laggard had completed the acquisition, but except for the server moving Yanjing, there was not much change, he is still fully responsible for the management of the forum, and he no longer has to worry about funds.

This was originally a good thing, but the trouble was that this boss never asked about the forum, which made Dong Qifeng a little confused.

Hundreds of thousands of bought back forums, except for the system replaced with discuz, everything else is ignored, which is obviously abnormal.

"By the way, I'll probably check it out later. Chen Qiaoshan suddenly made up for it, seeing that Dong Qifeng was a little surprised, he said with a smile: "The open-air barbecue there tastes good, I'm just going to eat and drink, you don't have to pay attention to me when the time comes." ”

Chen Qiaoshan is curious about these stationmasters, how to say that these people are also at the forefront of the trend.

Rebus said that pigs standing in the tuyere can go to the sky, maybe there are too few pigs who go to the tuyere, who has not fought through thousands of troops before going to the sky.

Today's QQ, there are many competitors, although they have the advantage, but they are also after several life and death, and the upcoming SNS social platform war is even more fierce, as well as takeaway, ride-hailing, payment, P2P finance......

Chen Qiaoshan saw very clearly that no matter which outlet, it was the golden pig that could fly to the sky, and without the blessing of capital, everything was delusional.
