"There is also competition between each type of cigarette, and the biggest reason for the different pricing is the quality of the tobacco leaves, and the poorer quality cigarettes often face difficulties in selling."

Lin Hao told the truth.

After all, the planting area of Taoyuan tobacco leaves is limited, and the tobacco leaves are also divided into three, six, nine and so on, plus the blending of spices, resulting in different tastes.

Eight hundred years later, cigarettes are a competitive market, and many cigarettes in childhood memories have gradually withdrawn from the market because of poor sales.

"How to solve it, Lin Aiqing don't sell it."

Previously, Zhu Di lit a Xuanhemen cigarette, and after tasting it, he felt that it was dull and tasteless, and he couldn't arouse any interest at all.

"The role of advertising is particularly important, for example, the Xuan Hemen in the hands of His Majesty can be launched during the Qiqiao Festival, and the advertising slogan is called smoking only Xuan Hemen, only one person in his life, and the main target is the market for young people."

……

Lin Hao showed a sly smile, before he crossed over, he had been poisoned by this kind of soft broad.

Zhu Di seems to have been opened by Lin Hao to a new world, and marketing can still play like this.

At this point, the showers have stopped.

Lin Hao led Zhu Di and his party into the city.

"Have you heard, what experiments are the county school students doing in the civic square, to join in the fun?"

The people of Taoyuan ran towards the county school.

The students who can be admitted to Taoyuan County School have a very high status in Taoyuan.

"Lin Aiqing, take me to see you, a student from Taoyuan County?"

Zhu Di was curious about how the students cultivated by such strange people as Lin Hao would be brilliant.

Lin Hao bowed his head and walked towards the Civic Square.

Taoyuan County Civic Square covers an area of nearly 1,000 acres, and at the beginning of its establishment three years ago, it was Lin Hao in order to enrich the entertainment life of Taoyuan people.

Over time, it has become the most prosperous area in Taoyuan County.

The Taoyuan students in white robes were divided into two groups, with more than a dozen horses lined up beside them.

"What experiment are you going to do today?"

Lin Hao stepped forward and asked.

The person headed by the student, named Chen Lang, a native of Liangjiang Mansion, was studious when he was young, he could compose poems at the age of three, read through the Four Books and Five Classics at the age of four, and became famous in Liangjiang Mansion at the age of seven.

A proper nerd, eager to be buried in a book, conquered by Lin Hao with a book of calculus, and studied in Taoyuan County School.

"Master Lin, the students recently discovered that there is a force in the air, called atmospheric pressure, and today we will prove the existence of this atmospheric pressure."

Chen Lang held two hemispheres in his hands.

Lin Hao gasped, Magdeburg Hemispheric Experiment!?

And it is more than 200 years earlier than the historical Magdeburg hemispheric experiment!

"Nonsense, since it is a county school, it is not a county school, not to learn the four books and five classics, to learn what kind of duck is strong, so grandstanding, embarrassing."

Zhu Di's face was faintly gloomy.

I thought that with Lin Hao taking the lead, the students of Taoyuan County would be amazing, at least they could discuss the strategy of governing the country with themselves, but they never thought that it would be like this.

"Your Majesty, don't be impatient, what Taoyuan County teaches is a new type of curriculum, including mathematics, physics, chemistry, politics, history, and geography."

Lin Hao squinted his eyes slightly and gestured.

Zhu Gaoxu and Princess Xianning sat in the audience, eating fruits, and watching the performance on stage with great interest.

In his opinion, learning should be like this, what is the point of becoming a day with those old masters?

Chen Lang put rubber bands on the two hemispheres, filled the two hemispheres with water, and together they were together, and pulled out all the water, so that the two hemispheres fit together tightly.

"I wonder how many horses your majesty thinks will be able to pull these two hemispheres apart?"

Lin Hao said with a smile on his face.

"Why use horses, this king's hand is enough to pull away."

Cheng Guogong pursed his lips and said disdainfully.

Immediately afterwards, Chen Lang asked eight horses to be tied to both sides of the hemisphere.

With a wave of his hand, eight horsemen whipped the horses and galloped back, as if in a tug-of-war.

Gradually, the people around him let out an exclamation.

The horse's front hooves were raised and neighing, and the groom's face was red and covered in sweat.

But the two hemispheres did not move.

The look of drama and abuse on Zhu Di's face also turned serious, facing the beginning of the scene.

As a military general, he naturally knows how powerful a horse is, and eight horses can't pull this iron ball, which is simply sensational.

"If you can open the hemisphere, you will be rewarded with a hundred taels of silver per person!"

Lin Hao cheered.

When the groom heard this, he became more and more energetic, and kept waving the whip in his hand.

The horses kicked up puffs of dust, but the iron ball remained unmoving.

Zhu Di and Cheng Guogong glanced at each other, stepped forward and stepped on the horse, waving the whip in their hands.

The crotch was clamped between the horse's back, and the horse exerted its strength again.

As you can imagine, the iron ball is still the same.

Zhu Di and the two were exhausted, turned over and dismounted, and were really shocked.

"Taoyuan people, you should believe it, the atmospheric pressure exists, and it is very strong, and the air in the two hemispheres is pumped out in the experiment, so that the number of air particles in the balls decreases."

"The atmospheric pressure outside the ball pressed the two hemispheres tightly together, not to mention eight horses, even if sixteen still turned out to be the same."

Chen Lang breathed a sigh of relief.

The other day, he had pumped the air out of a sealed wooden barrel, and the barrel was crushed with a thud.

After pondering and pondering, I came to such a conclusion, and now it has been confirmed, and the sense of accomplishment is overwhelming.

"Father, the son thinks that the palace should also be taught in the same way."

Zhu Gaoxu's eyebrows fluttered and he came to Zhu Di's side.

"After all, it's a side-by-side way, what's the use?"

Zhu Di shook his head.

"Master Lin, this is a well built by students using the principle of atmospheric pressure."

Chen Lang seemed to hear what Zhu Di said, and pulled Lin Hao to the side.

Lift the well covered with a red cloth.

The people were amazed, that is, the well, why there was no water intake.

On the ground, there is a cement pillar with an iron rod at the top.

Lin Hao was full of appreciation, but he didn't expect Chen Lang to draw inferences from one case and study the pressurized water wells of later generations.

Chen Lang poured a glass of water into the pressurized water spout, and then pressed the lever.

In a moment, clear spring water gushes out of the water outlet!

This scene really shocked the people present.

"Physics is not a sideshow, there are physical phenomena everywhere in life, the pressurized water well through the lever, constantly compress the air into the well, so that the atmospheric pressure in the well increases, the well water is pressed out."

"Nowadays, the people of the Ming Dynasty make the wells, in direct contact with the air, often fall into filth, the water quality is worrying, if it can be replaced with pressurized water wells, the sanitary conditions will be greatly improved."

Chen Lang snorted coldly and spoke eloquently.

Zhu Di suddenly felt extremely embarrassed, indeed, as Chen Lang said, if this pressurized water well can be popularized in Daming, it will be of great benefit to people's livelihood.

"Even so, the Four Books and Five Classics, arithmetic is orthodox, and those who study are not famous for the examination and become officials in the court?"

Zhu Di finally found a bit of balance, no matter how good you are, it is impossible for you to gain fame in the test.

"Dare to ask Your Excellency, how much is the current prime minister a year?"

Chen Lang asked.

"It's worth seven hundred taels of silver, and ordinary people can't earn it for a lifetime."

Zhu Di said proudly that the Ming officials are definitely not low.
