Many things are cyclical but capricious, to say that now Mr. Big avoids his appearance, Chinese feel that he does not feel like Chinese, and foreigners do not agree that they are the same kind - but in later generations, such mixed-race looks may become a symbol of "noble luxury". It's also helpless.

A conversation with Mr. Big solved a lot of doubts in Lu Zhuhu's heart, and emotionally recognized a lot with the prince who gave Xi'er's name, and felt more and more why they are all the descendants of Mr. Big, and those people in the Mo family are rarely so reasonable......

Maybe it's a descendant of Miss Jinhua, but don't believe it...... Speaking of the eldest lady, even if she did her a small favor today, she may not appreciate it with her temperament......

Lu Zhuhu and Mr. Big walked out of the study, and Mr. Big suddenly smiled again: "Why do you say why your grandfather likes to eat a 'vinegar fish' the most?" I heard him say that when he was ruling Jiangning County, when there was a local flood, he was in a state of braving the rain and wind, and he could only bring two dry cakes, and when he was hungry, he soaked them in muddy water and ate them. As a result, one day the common people caught a fish on the dam and cooked it for him, he was not a poor and exquisite person, but it was the time of the disaster, and he was not so particular about cooking, and the phosphorus was not scraped and the meat was not cooked, it was earthy and fishy, and the spirit of sleepless was very poor, and he almost vomited out the contents of his stomach - but that was the intention of the victims, maybe he didn't eat to pay tribute to your county official, are you embarrassed to vomit? As a result, it was seen and said, "Master, I still have altar vinegar at home, bring it to you." It's good to have vinegar, it's good to have vinegar - I'm happy, I saw a fierce man get into the water, swim back to the flooded house, and really bring him vinegar——"

"I didn't let go of anything else, I poured a little vinegar on it, and ate it very deliciously—but after the disaster had passed, I couldn't find this person anymore. It is not easy for the people who are affected by the disaster, and he is greedy for half a bowl of vinegar for a fish, and he is uncomfortable. But in the future, he preferred this dish the most, he made a fork by himself, and brought his own fish when he came to eat at home, and then said, "Come to rub your vinegar again", ...... "After many years, I can vaguely see the happy look when he saw the person who came to the family to "rub rice", as if Zhenfan was a guest of Lu Zhuhu today.

It can be seen that Mr. Big misses the days when he had this elder when he was a child, but this is the story......

Why does it sound so much like making up......

Prince Ma once summarized China's "four famous folk cuisines": Zhuge Liang, Zhu Yuanzhang, Qianlong, and Cixi, and basically the stories on the walls of various snack bars are related to these four, and they find different ways of eating. Zhuge Liang is "inspired" (inventing steamed buns), Qianlong is "unintentionally" (lost his way, the villagers send food, Qianlong will be full of praise when he eats it), Cixi is "in a hurry", only Zhu Yuanzhang is the worst is basically in the scene of "cornered......????

Judging from the routine of this story, it seems to be imitating Zhu Yuanzhang's routine......

Looking at Lu Zhuhu's performance, Mr. Big laughed: "Actually, I also think that it may be making up stories to fool children, I didn't eat well at that time, and they adults made up some stories of 'I can't eat when it's bitter' to coax me, when I think of others being so miserable, and the previous days were so miserable, I don't dare to eat badly anymore......"

Lu Zhuhu looked deeply appreciative, it seems that the routine of "remembering bitter and sweet" has been fooling children in my country since ancient times...... But in this matter, it is not necessarily true to say that it is all made up, at least Nanjing was really fond of floods in ancient times, and there was also a Yangtze River water backflow in the Northern and Southern Dynasties, resulting in a water depth of more than 3 meters on the imperial road, and the emperor Liang Wu Emperor was trapped, and the ministers had to row a boat to rescue him from the palace...... It is even more exaggerated when it comes to the situation of Lu Zhuhu, the old ancestor as an official, 15 times in the Daoguang Dynasty, 3 times in the Xianfeng Dynasty, 4 times in the Tongzhi Dynasty, 18 times in the Guangxu Dynasty, and 1 time in the Xuantong Dynasty...... On average, Nanjing will suffer a flood in less than three years......

Does it matter? But think about the location of Mr. Big's old house - Shu'an Mountain, this is a high terrain place, and there has never been a hidden danger of flooding, otherwise why has it been a place where rich people have lived since ancient times?

Lu Zhuhu sighed secretly: Don't look at Mr. Big's childhood experience seems to be twists and turns, but the rich and the poor are really different from the moment they are born, he doesn't have to worry about food and clothing, and he doesn't have to worry about the triennial flood. More people in the same period may have lost everything in the disaster, and their families have been ruined......

At this time, let alone the gap between the Mo family, which has experienced several generations of prosperity, and the family of three generations of poor peasants like him. When he was a teenager, he would still be indignant at the injustice of fate, but now he can only recognize the reality.

Hehe, I can be a guest of honor in your eldest family for a while, and I have come here in vain—Lu Zhuhu said to himself to a nasty young man who had not yet been born.

He and Mr. Big were talking inside, and the eldest lady saw that they hadn't come out for a long time, so she talked to the family about other issues—when Lu Zhuhu came out, he heard what seemed to be talking about London buses:

"We are now planning to launch two models of buses in London, and the previous test run has already been tested in practice, which is not bad......"

"It's just that how to invest is still a headache, and there are three or four plans for us now, one is that from the first year to the fourth year, we need to invest at the beginning of each year and recover 115% of the principal and interest at the end of the next year; Then the one requires investment from the beginning of the third year and recovers 125% of the principal and interest at the end of the fifth year, but stipulates that the maximum investment does not exceed £400,000......"

When it comes to business matters, the eldest lady seems to be a different person, serious and meticulous. Lu Zhuhu asked, "Miss Jinhua has already started to help the family do business?" ”

Mr. Big nodded: "It's not bad to study now - I made an appointment with her, give her a sum of money, let her do whatever she wants in five years, if she can double it - I will also allow her to handle the family business in the future......"

Lu Zhuhu nodded: "You have set a 'small goal' for her." ”

Seeing that they came out, the eldest lady wanted to ask if there were any results about her and Lu Zhuhu's eldest brother - as a result, as soon as these two people went in, they had forgotten the topic at the beginning from their background to the first Olympic Games.

The eldest lady didn't get any useful information from their faces, and said a little absent-mindedly: "Then what can I do to make him—ah no, how to determine the amount of investment to be given to these projects each year, so that the total principal and interest of the funds owned by the end of the fifth year are maximized?" ”

Lu Zhuhu didn't expect that the eldest lady actually paid more attention to emotional issues, but she was amazed that she was doing such a big business at such a young age, it was hard to imagine that this was just a teenage girl, like him at that time, such a big girl, just the appearance of a senior in high school, how could he worry about this?

Ah no, they also learn advanced math, and all day long the "which scheme is the best solution" linear programming problem...... But speaking of which, Miss Mo is not solving high math problems, she is playing with real money......

It's just that the eldest lady is now undecided, and when she talks about problems and lists data, she is a little upside down, and the more she calculates, the more confused she becomes, so that the big gentleman who set up an inspection period for her shook her head secretly.

"Huh? I heard that you studied mathematics and economics in Japan. That's not worth mentioning to you! Mr. Big laughed.

Lu Zhuhu smiled awkwardly, thinking that talking on paper and practicing are two different things.

Mr. Big said to Mo Jinhua: "I told you a long time ago, it is not possible to do it behind closed doors, let you ask more people and you will not ask-look at your Uncle Lu, I heard Ambassador Cheng say that when he was in Shanghai, everyone said that his knowledge was higher than that of many big professors, and I didn't see you thinking of asking him for advice——"

Lu Zhuhu was just about to be modest, when suddenly there was someone next to him:

"This little problem is not complicated, I don't need to make a move from Master Lu, I will solve it!"

Lu Zhuhu then thought that Xiaohua, this kid is still there! - After being hung for a long time, I was already a little impatient, and I didn't have anything to do.

Lu Zhuhu just wanted to let him settle down, but he saw this raunchy Fudan high-achieving student stretch his waist, stand up and say, "I've listened to you for a long time, and I haven't seen any big names!" It's just a 'simplex method' problem......"

"Simplex method?" It has always been the eldest lady who is not polite to others, and it is the first one to babble so much in front of her, but the eldest lady has never heard what he said, so she didn't dare to say more.

"Got a pen? Who gives me a - you see, the decision-making variables of this problem, we set the investment amount to be invested in A, B, C, D projects in the ith year - "Hua came uninvited, and he wanted to be a teacher on the spot, but he had a clear mind, solved the problem in an orderly manner, and the eldest lady, who was still a little half-hearted, looked at it twice and focused her attention, and even the big gentleman came over to stop and watch."

"Here, let's start modeling, the steps are—"

"Model solving, let's take a look at this optimal investment plan——"

"Look, by the end of the fifth year, you have a total of £183,750, and a profit of 83.75% – not enough of what your dad said!" Hua finished the calculation at a flying speed, threw the pen, and finally had the demeanor of a first-class university student since he went to the banquet.

But after the calculation, looking at the numbers, Xiaohua herself also has some incredible appearance:! Not to mention the income, just look at the principal given by Mr. Big......

Uh, you're really rich......

I was a little uneasy for a while, although he was condescending in terms of "knowledge", but the other party was a person who could use wealth to smash himself to death......

Mr. Big has received a traditional education since he was a child, and he has not been exposed to theoretical knowledge as the younger generation, so he doesn't know much about it, he looked at Lu Zhuhu tentatively, Lu Zhuhu glanced at the achievements of Hua Xue, nodded to Mr. Da, expressed his approval of Hua's method, and then patted Xiaohua's shoulder and said: Yes, I didn't learn in vain!

In 1947, in the face of the problems raised by the United States when formulating the military planning of the Air Force, Danzick first proposed the simplex method to solve this kind of extreme value problem, and in 1953, in order to improve the carry error accumulated in each iteration of the simplex method, Danzick proposed to improve the simplex method, which is a method often used in later operations research, which may not be a big deal for ordinary college students in later generations, but it is enough to win the Nobel Prize in economics in this era......

Lu Zhuhu thought that when he talked to students about these problems on the Fudan campus, he didn't plan to "start a sect" or anything, but even a "mixed" student like Xiaohua could master it, and Lu Zhuhu still had a great sense of accomplishment.

"Haha, famous teachers produce high apprentices, so it seems that all the students who break the captives are not idle people! - I just encountered some problems here, which are not easy to solve, and you have always been busy, so it is better to let you stay for two days and help with the details? Mr. Big invited.

Lu Zhuhu smiled: "That's what you can afford!" But if there is a need, it is naturally an unshirkable responsibility. It's just that he thinks Xiaohua is still a little reckless - with his own personality, he doesn't dare to buy an early morning and think about it, and as a result, people's big business of 100,000 yuan directly points fingers......

But everyone already values it very much, so what if you don't agree......

"It's not impossible for me to stay." Xiaohua said with a serious face: "Will the house still burn pig's trotters these days?" ”

Lu Zhuhu: "...... "You kid can die if you don't mention what you eat......

……

Lu Zhuhu left Xiaohua for Mr. Big to be a dog-headed military advisor, and he said goodbye first, but thinking that Mr. Big's biological mother was still in Greece, after all, the Jews there would be very miserable in the future, Lu Zhuhu still reminded Mr. Big that it was best to pay attention - that is, he did not explicitly say that Hitler was going to commit genocide in the future.

At that time, it would be nice to let him, a would-be "heroic mother", go to Shanghai to have fun - anyway, during World War II, Shanghainese also rescued many Jews, even Albert Einstein.

Mr. Big asked Jinhua and Zhenfan to give him a ride.

Seeing that the eldest lady always had something to say, Lu Zhuhu could only open Zhenfan, wanting to ask her what medicine was sold in the gourd today.

"Damn, you really want to be my sister-in-law!" Lu Zhuhu shouted with his mouth wide open.

"What...... Ah...... It's not ......" The eldest lady didn't know how to explain, ashamed and annoyed.

"Uh, how can I say it, Brother Da Long, it's hard to say, it's hard to say...... "Lu Zhuhu can't say that this person has long returned to modern times, and he is not in Göttingen at all......

"Actually, I think Ye Shuhong Gongzi is still very good, it's worth considering, if you miss Ye Gongzi because of Brother Dalong, it's a bit of a pity!" Lu Zhuhu pondered, looking at the meaning of the two families, he wanted to match these two young people, don't they were originally a couple, but Brother Da Long crossed over and teased the girl's heart, so that it would be bad if he couldn't play a piece in the end......

"What!" The eldest lady pouted: "I didn't like him in the first place!" Even if I didn't—I wouldn't want to be with such a boring person...... Alas! Forget it, anyway, if you can help me out of the siege today, I still have to say thank you to you......"

"Alas, Brother Da Long is actually nothing good...... "Looking at the little girl, Lu Zhuhu felt a little pitiful: "If you can, it's okay to consider other young talents, such as——"

"Which one?"

"The student I brought today is very good, very handsome, funny and humorous, good at learning, and can play football......"

Mo Jinhua: "......"

"If you don't want to, I still have a student, more-"
