It's not that Qu Sa's sales model is good, her business is booming, one is fresh, the other is sweet, and the most important thing is that she is more flexible than others.

This piece does not earn that piece, the wool comes out of the sheep, as long as you remember this, you will not suffer. If you want to earn more for everything, it's not smart, it's greed, and you may not earn any money.

More than 600 yuan of clothes earned more than 200 yuan, such a profit, such a speed made Qu Sa satisfied, but also made his peers envious and even jealous.

However, this is a big city, the industry is regular, the management is strict, Qu Sa is also a serious person who has paid the management fee, even if someone is red, he does not dare to make trouble.

The stupid one walked around in front of Qu Sa for a while, but the smart one followed Qu Sa's example, so in one day, several peers also engaged in the "buy one get one free" or even "buy one get two free" activities, and the results were quite good, and they all tasted the sweetness brought by this operation model.

Unconsciously, they were very grateful to Qu Sa, and those who were jealous put away their malicious eyes and imitated them.

However, there are too many stupid people in this world, many people only learn the watch but do not learn, and after a few days, a lot of things are sold, but they don't make much money, and even, some of them are not as good as before.

didn't make money but didn't reflect on her own shortcomings, but instead put the blame on Qu Sa, saying that she, a foreigner, did not abide by the rules of the industry, set prices indiscriminately and destroyed the market, and threatened to drive Qu Sa out of the pedestrian street.

No, several people have joined forces to report the situation to the Industrial and Commercial Bureau, so on a breezy weekend, several managers came to Qusa's booth to investigate.

……

Last time, the sales of pleated skirts were excellent, and Qu Sa took all the money from the profit as a cost, and bought an extra twenty pleated skirts.

However, this time she didn't take the buy-one-get-one-free route, but changed to a 20% discount for regular customers. In the past few days, she has basically an impression of the faces of girls who buy her pleated skirts, not only can she tell when they bought the pleated skirts, but also have a memory or two of the situation at that time.

Some students deceived Sa when she was young, deliberately licking her face and acting as an old customer, and she was ridiculed one by one.

When several administrators arrived, Qu Sa was "teaching" a cheeky boy, "Big brother, I really want to treat you as a mature person, but I also have to have the number you wear here, look at you, the lowest person who is tall and tall has to wear this number!" ”

Qu Sa stretched out his finger to gesture, then turned out all the numbers of her clothes for him to see, and then said sincerely: "Actually, it's no problem if you want a discount, just find an acquaintance to come over, and you two can go to the snack street for a little rubbing with the money you save." ”

Although Qu Sa was kind, the boy didn't appreciate it, too, there are so many people around, he is so ugly, it's no wonder that he is not angry.

The boy's face was horizontal, the blush receded, and he said coldly: "Little sister, let's be kind!" Whether I bought it or not, we both know each other in our hearts, you can't deny the past just because you don't have the number I wear now, and it's really a poor mountain and a bad water! The boy said very ugly, thinking that he had saved face and got up to leave, Qu Sa sneered and stood up violently.

"I said this big brother, are you really a college student? How come you have read all the books for so many years and read them all into the belly of a dog? is still poor mountains and bad waters, how can the mountains and rivers of my motherland become poor mountains and bad waters in your mouth? Still Diao Min? Which official are you? Which bowl of rice are you eating? ”

The boy didn't expect Qu Sa to be so eloquent, so he said angrily: "I am a junior student of the design department of East University of Science and Technology, and you country girl dare to insult me like this!" Do you know what a design department is? Do you know what courses I usually take? The boy trembled angrily, and in a hurry, he showed Qu Sa the book in his hand, "Do you know what this is?" ”

Qu Sa was completely speechless, she had lived for two lifetimes, she had really never seen such a strange thing, saying that this thing was so virtuous, how did she survive until now?

Qu Sa's eyelids drooped and glanced at him, "Mathematics." ”

"Yo, you're still literate, do you know what math this is?"

"Advanced Mathematics." Qu Sa replied expressionlessly.

The boy paused, and his smile became even more invisible, "Do you know what advanced mathematics is?" Do you understand what it's about? As he spoke, he casually flipped a page, Qu Sa glanced at it again, and said with a blank face: "Lagrangian median value theorem." ”

It was about the place where the boy's thumb was inadvertently swept, and as soon as her words came out, the audience was silent.

There are almost all college students around, and they all know exactly what Qu Sa said, a country girl who is setting up a stall actually knows the Lagrange median value theorem? I'm afraid it's a coincidence, right? None of them believed it was true.

The boy who made trouble was even more shocked, almost stiffened in place, and after a few seconds, he suddenly laughed, "Dare to show off if you recognize a few words, haha, haha, I have never seen such an ignorant person!" ”

The boy thought that Qu Sa was just reading the words in the place where his thumb was, and that he was not saying the theorem out of thin air. The boy reacted like this, and there were many people around him who reacted, and couldn't help but want to go with the boy.

Yes, a girl from the countryside, who seems impossible to read in high school, how can she know something as complex as the Lagrange median value theorem?

Qu Sa glanced at the boy with disdain, brother, since you are shameless, then don't blame your aunt and grandmother for being polite!

"The junior is holding the calculus of his freshman year, and he is embarrassed to laugh at others here, big brother, have you failed the course? How many times have you made it up? Haven't you made up from freshman year to junior year? Be careful not to get your diploma! ”

This time, the audience finally fell silent.

Knowing that theorem is not a skill, after all, the book is opened, and those words are revealed, but if you know that this book talks about calculus for no reason, then ...... It was difficult for everyone to find the right words to describe it. What's more, Qu Sa clearly said that calculus is a course to be taken in the first year of entering a higher education institution, and most majors in most universities in China are like this, because calculus is the most closely connected with the senior high school course, which can be said to be an extension of the senior high school course......

"You! You are talking nonsense! You've just failed! "The boys are in a mess.

Qu Sa understands that in these years, the style of study is still simple, even if the grades are not good, there are few students who fail the course, unlike some universities in the next one or two decades, some students' mastery of knowledge is simply not the same.

Qu Sa smiled coldly, "If you want to understand integrals, you must first learn differentiation well, in general, integrals are easier than differentials, so big brother, go back and study differentials and then look at integrals, don't fail the course again, be careful that you can't get a graduation certificate after graduation, and the university will be in vain." ”

Several administrators nodded their heads in shock when they saw this.
