> Yang Rui sat in the classroom and couldn't help but take out a small notebook and record his earnings.

So far, Yang Rui has accumulated three dividends.

The WestJet factory with full horsepower is the most stable earnings, with a profit of $600,000 in the quarter last year, which was distributed to Yang Rui 150,000, and this year's estimated profit should be 3 million, which means that Yang Rui can get more than $800,000. However, the final profit will be affected by the semi-chemical synthesis plant, and the Japanese plant can maintain such a profit for another year if the equipment is completely renewed.

Ruijie factory is under construction in Tianjin, with the support of the local government, the progress will be extremely fast, is expected to start in the second quarter, can enter production, and Yang Rui, who owns 34% of the shares, may get three times the income of the WestJet factory in the first quarter.

The premium is a windfall, with an annual output of more than 5 tons and a premium of $750,000 per ton, which means that after the factory is fully put into operation, the annual income will exceed $3.65 million!

This year, he will be able to get at least $600,000 from the WestJet factory, and if he is lucky, he can get $800,000, and if the Ruijie plant is put into production in the second quarter, he may be able to get a share of $1.8 million, and the royalty will probably be obtained from the second half of the year, which is also 1.8 million, plus the $800,000 license fee that has been obtained, and the $300,000 equity capital that will be expended, his expected income in 1983 will be $4.9 million.

Although this kind of income is not as good as that of his counterparts in European and American biological companies, Yang Rui is already very satisfied, to be precise, he is simply crazy.

Even after 30 years, there are not many bio companies that can make $4.9 million.

It is true that under the stimulation of the high-tech industry, the development of biotechnology companies is in full swing, and small biological companies with profits exceeding 100 million yuan or purchasing more than 1 billion yuan have emerged at every turn, and what is researched and manufactured is still boring things that ordinary people can't understand at all.

However, net profit and operating income are different after all.

For a small technology company in Europe and the United States, the operating income of $4.9 million is at most to keep the company alive for a year, which is not a remarkable achievement in this era when the average survival of a biological company is 36 months.

A profit of $4.9 million is different, in fact, the biological companies that have just begun to grow exponentially have burned a lot of money and made very little profits, just like the Internet companies in the 90s.

Small and medium-sized biological companies that need $30 million and $50 million a year are popular in Europe and the United States, but if you want to say that they are profitable, you can't pick out two out of 100.

is also studying coenzyme Q10, if Yang Rui didn't know the answer earlier, read the complete paper and related research, and then compare it to the real one, refining solanesol alone, it is possible to use millions of dollars, and the semi-chemical synthesis of coenzyme Q10 is a big pit, and it is not surprising that it cannot be made with 10 million or 50 million US dollars.

Because of this, Jielikang is willing to cooperate with Yang Rui, while Japanese companies prefer to produce while fighting lawsuits.

Yang Rui took a breath, turned a page, and began to record the instruments he wanted to buy. A refrigerated centrifuge seems to be needed, an electrophoresis apparatus is also needed, a nitrogen fixer is also wanted, and a particle size meter seems to be useful, and it would be better if it is a laser one......

Yang Rui easily wrote half a page, was stunned for a moment, and then drew a cross with a pen.

The real yàn room is like an audiophile with a computer, selling speakers, there will always be a better one, and no amount of money is enough to spend.

Let's start with the technology at hand.

Yang Rui was thinking about it, and a shadow blocked the light.

"Yang Rui, there is a question. Xu Jing's voice sounded good, but her body was really strong, like a female weightlifter.

Yang Rui thought for two seconds before realizing that he was in a self-study class, so he closed his notebook and picked up Xu Jing's workbook and read it.

"It's a three-dimensional geometry. Yang Rui often sighed.

Xu Jing glanced at him inexplicably and said strangely, "Yes." ”

Yang Rui nodded, and while looking at the question, he asked, "How many students can solve three-dimensional geometry in the class?"

"There are more than a dozen people in Hongrui's class. Xu Jing gave a rough number and asked, "What's wrong?"

"Sigh a little. Yang Rui smiled and shook his head.

Xu Jing was a little funny and said: "What is there to feel emotional, the teacher talks on the stage every day, and it will be okay if it doesn't." ”

"If only I could. Yang Rui continued to sigh.

Science has never been a subject where the left ear goes in and the right ear goes out, and you can get a long score by listening.

In high school mathematics, solid geometry is absolutely difficult, especially for students who do not have a solid foundation, any solid geometry problem is hellish difficulty.

To solve the solid geometry problem, first of all, you have to be familiar with the plane geometry, if the plane geometry problem is done very well, the solid geometry does not need to be thought, it can be done all by luck.

In the era of the high school entrance examination, 120 points must have at least 100 points of mathematics scores, in order to say that the basic mastery of plane geometry, with the study of high school, the knowledge is gradually broadened, the students who scored 100 points in mathematics in the high school entrance examination in that year, and then take the test, maybe 110 points, or even 115 points, at such a level to learn three-dimensional geometry, in order to say that there is a good foundation, so as to get an excellent score in the college entrance examination, that is, about 85% of the score.

In other words, if a student who has just started his first year of high school and learns three-dimensional geometry when he meets, his score in the high school entrance examination should be 110 or 115 points to qualify. Many key middle school key classes are also recruited on this basis, they spend about a year to complete all the courses in high school, and then participate in various competitions to get guaranteed places, and some unknown parents try their best to send their children to such classes, the results are often not satisfactory, which is also a similar reason.

Ordinary high school students usually don't get close to a perfect score in mathematics, so most students will still have a headache when they learn three-dimensional geometry in the second and third years of high school.

Students with a score of 100 in the high school entrance examination have a headache and can more or less complete the study of three-dimensional geometry, and students with worse grades in junior high school, even if they have a headache, often do not understand the study.

For the latter, re-studying plane geometry in junior high school is the only way out.

Of course, this is not easy. Junior high school mathematics is a total of two major items, plane geometry and algebra, plane geometry that took two years to read, it is very simple for those who have learned to reread, let those who have not learned read again, and it is in high school where learning is intense, and the pressure can be imagined.

Later generations of full-time students who studied in 6-year secondary school found solid geometry difficult, and for students who studied in 4-year middle school in the 80s, solid geometry was even more difficult.

Looking at the size of the college entrance examination, where there is a lot of three-dimensional geometry, the national average score will definitely fall, for such topics, even Yang Rui, can only be difficult to deal with some useful and useless skills, and is not sure whether it can play a role.

In short, it's a series of questions that look at the fundamentals, and unlike functional probability, etc., solid geometry is a test of the fundamentals of the entire secondary school years.

In this regard, in addition to listening to lectures and practicing hard, it is not easy to get a passing grade in three-dimensional geometry.

There are more than a dozen people in Hongrui's class who can make three-dimensional geometry problems, even the simplest three-dimensional geometry problems, Yang Rui feels that it is not easy.

With the current difficulty of the college entrance examination, it is enough to be able to make simple three-dimensional geometry questions.

In terms of scores, as long as the score is more than 50%, you can basically be admitted to the junior college, and if the results are assigned to each knowledge point according to the difficulty, the three-dimensional geometry does not need half of the score at all.

Of course, it always doesn't hurt to get a high score.

Yang Rui wrote down the disintegration steps, handed them to Xu Jing, and said, "Let's see if you can understand it first." ”

Xu Jing moved a bench and sat on the side.

After a while, another student came to ask Yang Rui the question, and Yang Rui answered while judging everyone's Cheng dù.

It has been more than half a year since the establishment of the Ruixue group, and everyone has greatly improved, but the gap in scores has also become obvious. For the same question, some people are plausible, some people don't understand it at all, and they all get zero points, after practice, people who used to be plausible can now get full marks, and people who didn't understand at all before can get half of the scores, and there is naturally a gap in the scores.

"Let's divide it into a fast and slow class. Yang Rui came to Wang Guohua to discuss.

Students' grades are slowly increasing, and it is impossible for a teacher to take care of all students, and there are always people who are abandoned in the course.

Divide the class into better lectures and exercises.

Wang Guohua said unexpectedly: "Students who are assigned to the slow class will have ideas." ”

"I can explain to you, if you really can't figure it out, you can't do it. ”

Wang Guohua twisted a knot on his forehead and said, "How do you explain it?"

"Hongrui's class is a class that aims for the college entrance examination, and any behavior that does not aim for scores is a hooligan. In addition, if you have bad grades and can't figure it out, you can automatically apply to withdraw from the Hongrui class and Ruixue group. Yang Rui's idea is very clear, he used to be a tutor, he does not have all the constraints of public schools, his goal is to make up lessons for students who want to go on to higher education, and use all the methods to allow students to get high scores.

Wang Guohua was still a little entangled and said: "Tian Shichang is no longer studying, and he is still a member of the Ruixue group, just because of the fast and slow class, isn't it okay?"

"Naturally, the official team members cannot be expelled directly...... Okay, don't worry about it so much, I don't believe that students are so fragile, is it that in a class, there are no grades?"

"That'...... Shall I just let me know?"

"Wait, one more sentence. Yang Rui pondered for a moment and said: "Don't talk about fast and slow classes, let's just say that one is a heavy class with the goal of all students and some people, and the other is a general class with the goal of all students and some people, so it sounds a little better." ”

Wang Guohua was speechless: "It's too arrogant, this makes the students in other classes see it, and they don't laugh at us?"

"I didn't know the scum of guò in the pre-exam, what qualifications do I have to laugh. Yang Rui pursed his lips and said: "Xibao Middle School has not been admitted to a college student before, this time I removed our Hongrui class, and the result is estimated to be about the same, so I don't need to pay attention to them." ”

"What if I can't pass the exam?" Wang Guohua blushed a little and said: "I sometimes worry that this exam room is different from the mock test, what if the score is not enough, there are so many people in our Ruixue group, we can't all be admitted." ”

What Yang Rui wants in his heart is to be admitted, but the college entrance examination can never be a sure thing. Yang Rui thought for a while and asked, "If, I mean, if you don't get in, what do you want to do?"

"It's going to be another year. Wang Guohua said without hesitation.

Yang Rui smiled: "That's not what I mean, I just said, if you don't go to college, what do you want to do?"

"What else can I do when I go back to my dad's class. Wang Guohua's voice deepened. His father is the director of the post office, which is a good position, if there is a chance, he can still recruit him in. However, in the case of high unemployment in the whole society, it often takes several years to recruit workers, and at this time, the only way is to replace them. Wang Guohua's father applied for retirement, and then let Wang Guohua make up for it.

Although it can solve the problem of work, for teenagers, this way of looking for a job will not always make people morale.

"What do you want to do, that is, if you want to learn a technology, what are you willing to learn?"

Wang Guohua knew that Yang Rui was not asking in vain, thought about it carefully, clenched his fist, and said, "Be a driver." ”

"As a driver?"

"Stethoscope, steering wheel, labor section chief buyer, stethoscope to study medicine, I don't like to do it, labor chief is an official, the buyer is very good, but not as good as a driver. Wang Guohua's analysis is the Tao. The four occupations he mentioned were also the most affordable jobs in the 80s, not only did they pay well, but they didn't need to ask for help, but there were countless people who came to ask for them. In layman's terms, these four professions are the ranking of the mother-in-law's favorite son-in-law occupation.

For example, doctors' diplomas are generally higher, doctors' salaries are generally higher, and in the case of national publicly-funded medical care, doctors with prescribing rights can help people prescribe good medicines, prescribe more medicines, not only earn favors, but also receive a lot of gifts.

The driver is a little worse than the doctor, but there are also countless aura deepenings. First of all, driving is a technology, especially in the 80s, the car failure rate is high, and it is necessary to learn to maintain while learning to drive, which is equivalent to both maintenance and driving technology, which is very rare. Secondly, the drivers all have a background, because there is a unit with a car, it must have a background, it is naturally the best to drive a car for the leader, and it is also very good to drive a truck, because vehicles are scarce, help people bring goods, and even help who transports goods first, can breed small ** out. In the end, the driver traveled from south to north, well-informed, and his conversation was not elegant, which was better than being stuffed in a city.

For a small-town teenager like Wang Guohua, even if he is a driver, he can do what he wants. At present, there is no social driving school, and the formal channel is either to go to the technical school of the Public Utility Bureau, or to join the automobile class as a soldier, or to train in the unit, which is not simple.

However, it is still feasible to learn to drive first and then ask someone to take a driving school test, and many smart children who join the military do this.

Yang Rui pondered for a moment, made a decision, and said, "Then learn to drive." ”

Wang Guohua was surprised: "How to learn?"

"I buy a truck and ask someone to teach me. But not everyone can learn, and the members of the Ruixue group who can't keep up with the slow class can apply first, and then have free time and share it with others. ”

Wang Guohua was excited and asked: "Where to buy a car, where to ask someone for advice?"

"I'll figure out a way to do this, you can inform everyone first, now there are four months before the college entrance examination, I will try to buy a car within a month, find someone, and leave a way back for students who can't pass the college entrance examination without affecting everyone's participation in the college entrance examination. The more Yang Rui thinks about it, the more reliable he feels, he has a lot of foreign exchange in his hand, whether it is through the back door in China or imported from abroad, it is very simple to buy a car.
