Zhou Li and the book of rites both recorded the system of weights and measures. Qin Shihuang unified the six countries, and it is "one measure, stone and ruler, cars on the same track, books on the same text". Its fundamental lies in the unification of weights and measures.

Since ancient times, Chinese measurement has units such as length, weight and capacity. Now Li forgets worry and puts forward an unheard of "temperature". How can we not make people excited?

The high and true monks of Taoism and Buddhism are even more excited.

This is the immortal family Dharma handed down by Taoist ancestors!

Even if the beliefs of Buddhism and Taoism are different, it does not prevent them from listening to the "teachings of Taoism". After all, they are all heavenly dharmas, which are no different from the Dharma of Buddha.

After Li forgot to worry and attracted everyone's interest, he waved down, and someone immediately brought up some artifacts.

It doesn't matter what kind of stove, ice, water basin and so on, but one of the giant thermometers makes people feel fierce.

This thermometer, nearly one meter high, is a teaching aid blown out by Li QIAOYOU to the craftsman for teaching.

Although people don't know what a thermometer is, they can see that it is valuable.

This is nonsense, of course. These "bystanders" are not blind.

In the eyes of the public, such a huge stick shaped utensil like crystal is made of crystal clear material. It can be seen at a glance that it must not be ordinary.

Some people suspect that this is the colored glass produced by Daqin, but the colored glass of Daqin has never seen such a clear one.

Some people secretly speculate that it is carved with transparent colorless crystal.

But who has ever seen such a big crystal, and it is unimaginable to carve and polish the crystal into such a shape at present.

Whether it is crystal or glass, it is a treasure with a price higher than gold.

Even those Taoist gaozhen and Buddhist monks secretly speculate that this glittering stick is a "treasure" handed down by the Taoist ancestors to the Duke of Fufeng County?

They have even guessed that the temperature mentioned by Li forgetful before is related to the treasure.

Li Qieyou didn't sell off, and soon solved the mystery for the people.

"All living things in the world can be measured, and cold and heat can also be measured naturally. This is an instrument specially used to measure cold and heat, called a thermometer, handed down by the Taoist ancestors!"

In fact, the thermometer made by Li forgetful worry is only the simplest glass tube thermometer, which uses the principle of thermal expansion and cold contraction to measure the temperature.

Of course, with his knowledge, he can only come up with such thermometers. Other pointer thermometers, resistance thermometers and gas thermometers don't have to think about them unless there is a true manifestation of the Taoist ancestors.

"All living beings may ask, why do we need to measure cold and heat, and why do we need to measure temperature?"

"Simply put, temperature is life!"

Li forgot to worry about this, which immediately caused an uproar. Everyone began to write quickly and record his words and deeds.

Ma Zhou and others simply asked for leave today and came directly to listen to their teacher's lecture.

At this time, Ma Zhou and Yan Liben were not only taking notes seriously, but even thinking about it in their hearts. They should record all the teachers' words in a volume, and then print them into a book, which was widely spread in the world.

Li Qieyou gave a lecture on popular science knowledge about temperature for a quarter of an hour. Only his words echoed in the auditorium and everyone took notes.

The temperature in his mouth naturally refers to the centigrade scale used by later Chinese. As for what Fahrenheit scale, open scale, Liesl scale and Rankin scale, Li forgets worry neither understand nor bother to ponder.

In short, to teach nature is to teach yourself habits.

"Well, as I said just now, a person's temperature is about 36 degrees, boiling water is 100 degrees, and the mixture of ice and water is zero."

"All living beings, the cold and heat of everything in the world can be measured. Next, let's do a few small experiments to measure the temperature of these objects. Is it the same as what I told you..."

On the podium, Li forgot to worry about the concept of temperature and the use of thermometer to the college teachers and students and a group of "audience students". Then he took the giant thermometer as the teaching aid and measured various objects in public, which made everyone excited.

Then he ordered people to give teachers and students many thermometers of normal size and let them test them by themselves.

Li Qieyou didn't expect that there would be more than a thousand "bystanders" suddenly. Therefore, the number of thermometers ordered craftsmen to blow is limited.

In order to satisfy the uncontrollable curiosity of these "bystanders", Li forget worry can only let the teachers and students of the Academy give up a few thermometers and give them to these famous scholars to measure the temperature.

The teachers and students of the Academy were all right, but these famous scholars, eminent monks and officials almost didn't fight in order to compete for the right to use these thermometers.

"Amitabha, I got this thermometer first. Taoist priest, why compete with me?"

"This is handed down by the Taoist ancestors. What qualifications do you Buddhists have to compete with the Taoist priest?"

"Amitabha, Taoist priest, what's the difference between these words? In front of Taoist and Buddha, we are all equal. How can we make the difference?"

"Bah! Dead bald donkey! Stop talking so much nonsense and hand in the thermometer quickly!"

"The poor monk won't be with you. How are you doing?"

In order to snatch the thermometer, several gaozhen eminent monks, all of whom are nearly a thousand years old, sprayed saliva on each other's faces.

Fortunately, they also know that the academy can't let them mess around, so even if they quarrel, their voice is very low, and there is no possibility of doing it.

Other famous scholars and scholars, all officials and dignitaries are no better. They all lowered their voices and vied with each other for the right to use the thermometer.

There are many "smart people" among more than a thousand "spectators". After a fierce competition, I saw an old man suddenly stand up, bow to Li forgetful and ask, "excuse me, sir, do you know if this thermometer can be sold to me? I am willing to give ten liang of gold to buy it from you."

Li forgot to worry and was stunned when he heard the speech.

Someone wants twelve liang of gold for a thermometer?

Are you crazy?

This thermometer is just glass. Even if Datang's glass is expensive, its price is just equal weight gold.

How much can a thermometer weigh? I'm afraid he doesn't even have one or two weights, and this man is willing to buy ten liang of gold. Isn't that stupid?

Even if there are only 37 grams of one or two in the Tang Dynasty, ten liang of gold is also 370 grams. Based on the price of gold in later generations, it is also more than 500 yuan a gram, equivalent to more than 180000

Where is this thermometer? Is it good to grab it?

No, even if you rob, you don't have so much profit space!

How can Li forget you refuse such a good thing?

He was about to nod his head, but he saw that someone in the auditorium immediately got up and stood up: "Sir, I would like to give fifteen liang of gold, and please help me!"

"Amitabha, I'm willing to give you twenty liang of gold and ask Shizu to help me!" the Buddhist monk immediately stood up and shamelessly called Li forgetful as Shizu.

Moreover, Buddhism has never been short of money. There are only dozens of liang of gold, which has not been regarded by eminent monks at all.

Where can Taoist monks make Buddhism more beautiful than before? Buddhism doesn't need money. Isn't Taoism short of money?

Several gaozhen immediately got up: "Shizu, disciples are willing to give thirty liang of gold! Please sell these thermometers to disciples."

Rao Shili forgets to worry. He is used to all kinds of big scenes, but he is also bewildered by the scene in front of him.

The life of these rich people in the Tang Dynasty is really so simple and boring
