Lu Zhengyang has several amulets.

First of all, he is the leader, so he naturally has the final say on the rules at the dinner table.

Secondly, he has doctors’ advice to protect himself, so he cannot drink alcohol, so drinking a drink is an exception.

Third, he is an elder, and Gu Mingjun cannot force him to drink without reason.

And Lu Zhengyang can respect Gu Mingjun's wine with righteousness.

The first cup was his own toast, and Gu Mingjun had to drink it.

The second cup was to thank Gu Mingjun for his life-saving kindness for Lu Xiaolong, so Gu Mingjun had to drink it.

The third cup is to thank Gu Mingjun for saving Shu Yin. This glass of wine must not be ignored.

Shu Yin said that she was not good at drinking and used tea instead of wine. She respected Gu Mingjun, but Gu Mingjun had to drink it.

After drinking a few glasses of wine, Gu Mingjun said more.

The aged wine is really delicious, sweet and refreshing, refreshing, and drinking it makes people worry.

Before he knew it, a bottle of wine almost entered Gu Mingjun's stomach.

This wine is very sweet and I don’t think it’s so powerful. After drinking it, Gu Mingjun spoke clearly and spoke sharply, and was completely unintoxicated.

One meal, from five o'clock to six o'clock.

Lu Zhengyang answered a call and said to Shu Yin: "You take care of Mr. Gu, I have to go out."

Shu Yin said: "Dad, if you are having a social engagement, you must not drink."

"Don't worry, I know." Lu Zhengyang and Gu Mingjun sued and left on their own.

Gu Mingjun looked at the time and said, "It's getting late, and it's time for me to leave. I'm drinking this wine today."

Shu Yin smiled and said, "Mr. Gu, look, you can't drive after drinking, and we can't get a taxi outside. I want to bring Longlong with me. He is a tangled product, and I can't take it off to take you. Otherwise, you can rest at my house first? I'll give you it to you when my dad comes back, okay?"

When Gu Mingjun thought about it, this was the case and said, "It's just too much."

Lu Xiaolong ran over with his homework book and pestered Gu Mingjun to teach him how to do his homework.

Gu Mingjun took it over and looked at it, and smiled and said, "What kind of homework are you doing? Is it so difficult?"

"Mathematics homework." Lu Xiaolong replied.

Gu Mingjun said: "You are four years old in elementary school and you are learning such difficult math?"

Shu Yin said: "It is taught in extracurricular classes, mathematics Olympiad."

Gu Mingjun said: "Do you want to train him to follow the race?"

"I don't understand either, it was suggested by the teachers of their school." Shu Yin said, "If you want to go to four prestigious schools, you must learn Olympiad mathematics, otherwise you will not be able to keep up with other children."

Gu Mingjun was stunned and smiled and said, "I know why I am a poor student. Because I have never attended a training class."

Shu Yin said: "How is it possible? Are you still a poor student?"

Gu Mingjun said: "Really, I was a poor student in elementary school and junior high school. It was the year when I was in my third year of high school that I suddenly got my mind. Then I barely got into a university."

Shu Yin said: "Tutorial classes are very popular now. You start to learn the knowledge of junior high school in elementary school, and you start to learn the knowledge of high school in junior high school. Before the first year of high school, children who attended extracurricular tutoring classes had already learned the knowledge of the entire high school stage. If you haven't attended, you will not be able to keep up with their pace. But this gap will be even when you reach the third year of high school. Because everyone has learned all the knowledge. The college entrance examination competition is talent and the ability to learn from one example. You say that you change only when you reach the third year of high school, which just shows that you are a very talented person."

"Oh, after hearing what you said, it seems like this." Gu Mingjun smiled, "You can see it thoroughly."

He said to Lu Xiaolong: "To be honest, I don't understand your Olympiad mathematics very much, I can't teach you."

Shu Yinyanran smiled and said, "Let me see what kind of topic it is."

She sat next to Gu Mingjun, took the book, lifted her hair with one hand, and looked at the question.

"The two boys each rode a bicycle, and began to ride in a straight line from two places 20 miles apart (1 mile to 1.6093 km). At the moment they started, a fly on the handlebars of a bicycle began to fly straight towards the other bicycle. As soon as it reached the handlebars of the bicycle, it immediately turned to fly back and forth. The fly traveled back and forth between the handlebars of the bicycle until the two bicycles met. If each bicycle was moving at a constant speed of 10 miles per hour and the fly was flying at a constant speed of 15 miles per hour, how many miles did the fly flew in total?"

After reading the question, Shu Yin felt her head hurt and shook her head repeatedly: "Oh my God! So, I am dizzy, and I can't teach my children. I feel that the books I have had for decades have been in vain."

Gu Mingjun thought for a while and said, "Wait, this question is complicated, but it actually tests comprehension. Each bicycle moves at a speed of 10 miles per hour, and the two will meet at the midpoint of a 20-mile distance in one hour. The fly flies at a speed of 15 miles per hour, so in one hour, it flies a total of 15 miles."

Shu Yin smiled and said, "You are still great!"

Gu Mingjun said: "This person who set the question deliberately confuses people!"

Shu Yin smiled with a pursed lips: "That's not it!"

Lu Xiaolong quickly wrote the answer.

Shu Yin said: "The next question is more interesting. Mr. Gu, you are an investment person, and this should not defeat you."

Gu Mingjun looked at the question: "We all try to open a hotel with 80 suites together to see how knowledge is converted into wealth. After investigation, we found out that if we price the daily rent at 160 yuan, we can get full; and for every 20 yuan increase in rent, we will lose 3 guests. Each room with a person needs daily services, maintenance and other expenses totaling 40 yuan. Question: How should we price to make the most money?"

The difficulty of this question is obviously more difficult than the previous one.

Gu Mingjun quickly calculated and said, "I don't know if there is a standard answer. As for this question, the daily rent of 360 yuan is the most reasonable."

Shu Yin was also calculating. Seeing that he already had an answer, she asked, "How did you calculate it?"

Gu Mingjun said: "The daily rent is 360 yuan, although it is 200 yuan higher than the customer's full price, so 30 guests have been lost, but the remaining 50 guests can still bring us an income of 360*50=18,000 yuan; after deducting the expenditure of 50 rooms, 40*50=2,000 yuan, the net profit per day is only 160*80-40*80=9,600 yuan."

Shu Yin was amazed.

Gu Mingjun said: "I think this kind of question is not good. People who really work in hotels will not calculate it like this. The pricing is determined based on the market conditions. If you set the number of peers, you can only set the same. Too high or too low is a risk. There are also peak seasons and off-season prices, which are different."

Shu Yin said: "No wonder many academic masters are not good at doing business. They are completely different concepts in solving problems and doing business."

Lu Xiaolong doesn’t care about this much, he only needs the answer!

As soon as Gu Mingjun said it, he immediately wrote the answer.

Shu Yin said: "You kid, do you understand? You just write randomly? If you don't understand, it's useless to know the answer."

Lu Xiaolong said: "Mom, I can understand!"

Unexpectedly, it was quite interesting to do Olympiad math problems. The three of them worked together, and it was 9 o'clock in the evening before they knew it.

Lu Xiaolong usually goes to bed at 8 or 9 o'clock, and he didn't take a nap today. He was already sleepy. Although he forced himself to sleep, he couldn't resist the fight between his upper and lower eyelids and fell asleep on the sofa.

Shu Yin picked up her son to the bedroom. As soon as she got up, her feet slipped and both of them fell to the ground.

Gu Mingjun was quick-eyed and hugged her in his arms.
