Chapter 245
"Why did you call me here?"
Li Tai looked depressed and sat down.
Suddenly he found two drawings on the desk and curiously picked up a drawing of the men's toilet.
"What kind of building is this?"
Li Tai picked up the three-dimensional drawing of the public toilet that Su Chen had just drawn.
No matter how you look at it, you can't guess what it is used for.
If you ignore the problem of proportion, it looks more like a pigpen.
The dimensions have not been marked on the drawing, so the actual size cannot be seen.
There is a urinal in the men's toilet, which looks like a large pig trough.
"Is this a pig sty for sows to give birth next year?"
Li Tai asked uncertainly.
A few days ago, Li You said that the first batch of sows will give birth one or two months after New Year's Eve.
So Li Tai guessed that this was a delivery room prepared for sows.
Princess Changle chuckled, "Hahaha, this is... a toilet!"
"What toilet? Please use polite language!
This is called a public toilet."
Su Chen glared at Princess Changle and corrected her angrily.
These two siblings!
"Li Tai, let me ask you something. Have you ever seen a question about centimeters and meters in your math books?"
He has never read the books carefully since he got them.
At most, he looked at the cover and flipped through a few pages at random.
He didn't even think about the simplified Chinese characters in them.
"How could there be none? That's very simple. One meter is equal to ten decimeters, and one centimeter is equal to ten millimeters.
They are ten and one in turn."
Su Chen's head was big, just like a clock.
They just thought it was a math problem.
"Then do you know how long one centimeter is?" Su Chen asked again.
Li Tai shook his head. He wanted to ask Su Chen this question before, but he felt that it was useless in practical application.
"The book doesn't specify the size, how can I know?"
Li Tai answered as a matter of course.
Su Chen completely understood that there was no knowledge point about the conversion between the two in the math book.
"Tell me, how many feet and inches are one centimeter?" Li Tai asked back.
Su Chen was stumped and he couldn't answer.
But he suddenly remembered a question, he and Li Chengqian were almost the same height.
But Li Chengqian was definitely not 1.8 meters tall, at most 1.73 meters.
In his previous life, when he was in his twenties, he was 1.8 meters tall.
But he forgot that he was only sixteen years old now.
So Su Chen's height should also be more than 1.7 meters.
So we can draw a rough conclusion:
One foot in the Tang Dynasty is 33.3 centimeters.
"I can't explain this, how tall do you think I am?" Su Chen stood up and asked Li Tai to estimate his height.
He now suspected that Princess Changle's guess was inaccurate.
"No need to look, you and your elder brother are almost the same height. It should be about five feet seven inches, with a deviation of no more than five centimeters."
Li Tai said with certainty.
Glancing at Princess Changle, he remembered that Changle said he was five feet four inches tall.
Sure enough, it's unreliable...
At the same time, he calculated in his mind and concluded that one foot in the Tang Dynasty was only a little over thirty centimeters.
It's about 30.6 centimeters, not the 33.3 centimeters that are well known in later generations.
"Five centimeters?" Su Chen sat back in his original position and asked curiously.
He didn't know there were units smaller than inches before.
The things he was going to study later needed more precise units of measurement.
"One millet is called a fen, and ten centimeters is called an inch. This has been used since the Han Dynasty.
Millet is a kind of grain with relatively uniform grains."
Li Tai didn't find it strange that Su Chen didn't know about fen.
Su Chen nodded after listening and asked again:
"Why is there a saying of a seven-foot man? It's impossible that the ancients were so tall, right?"
When Su Chen asked this question, Li Tai didn't say anything.
Princess Changle laughed first.
"Hahaha, Su Chen, have you ever heard of 'real man'? Isn't it that a man is ten feet tall?"
Su Chen nodded.
"Do you know the origin of the word husband?" Princess Changle continued to ask.
Su Chen shook his head.
He really didn't know this.
"Su Chen, you can recite the Four Books and Five Classics, I thought you were familiar with history books.
It turns out that you are just that!"
Li Tai looked at Su Chen and smiled meaningfully.
"Tsk! Do you know the Yonghui Reign and the Kaiyuan Prosperity?" Su Chen retorted disdainfully.
Li Tai frowned and thought after hearing this.
"Which emperor's reign titles are Yonghui and Kaiyuan? There is no record in history books. You must have made them up!"
Li Tai was very suspicious. It was definitely Su Chen's fabrication.
"Stop talking nonsense. Tell me the origin of the seven-foot man and husband."
Su Chen waved his hand and said.
"Li Zhi, you come and explain it to the great immortal Su."
Li Tai was not interested in telling Su Chen about that. He picked up another drawing of the women's toilet and looked at it carefully.
Prince ChangleThe master nodded, she was very helpful.
Especially for Su Chen, this can make her feel a little superior.
"The origin of seven-foot man and husband is related to the evolution of size in dynasties.
For example: In the Shang Dynasty, one foot was about five inches and six points today, and ten feet was a zhang.
Therefore, ten feet was used to refer to adult men, called: husband."
After listening to what Princess Changle said, Su Chen calculated silently in his heart.
'5.6 times 3.06, one foot in the Shang Dynasty was about 17 centimeters, and ten feet was a zhang, which is exactly the same as the height of an adult. '
Su Chen finally figured out the correspondence between the size of the Tang Dynasty and centimeters.
He also had a clearer concept of feet and inches in his mind.
Princess Changle was a little confused when she heard the word "meter" again, and she continued:
"Devote a square inch to serve the country, forget seven feet to serve the king.
Have you read these two lines of poetry?"
Su Chen shook his head, why read those poems for nothing?
"This poem comes from Shen Yue of the Southern Dynasties. The seven feet in the poem means the body of an adult man.
During the Northern and Southern Dynasties, one foot was about eight inches and four points today."
Su Chen calculated again and found that one foot during the Northern and Southern Dynasties was about 25.7 centimeters. Su Chen was very surprised.
Did the average height of people in the Northern and Southern Dynasties grow so much?
Nearly 1.8 meters, perhaps there is an exaggeration in the poem.
No wonder Guan Gong is said to be nine feet tall.
"I understand now. The one foot you said is equivalent to 30.6 centimeters.
You also know how many feet and inches are equal to one meter now? Convert it yourself."
Princess Changle really took a pen and paper to calculate.
"One meter is equal to three feet, two inches and six points?"
Su Chen is not so good at mental arithmetic.
Nodding, he replied: "Almost."
Li Tai picked up two drawings and asked.
"Why are the layouts of these two pig pens different?"
Su Chen was furious.
"Fuck, this is a public toilet, not a pigsty."
Why don't you listen to me?
"What's the difference?"
"Look, there's a pig here... there's a trough, but this one doesn't."
Li Tai pointed at the urinal in the men's toilet and said.
Su Chen was so angry that he rubbed his face with both hands. Li Tai definitely wanted to say the pig trough.
"That's the urinal in the men's toilet, understand?"
Li Tai nodded as if he understood and asked:
"You called me here just to find out the size and inches, and show me what kind of toilet is this?"
Su Chen shook his head, "I want to ask you if the Tang Dynasty has a national flag."
Li Tai was sure that the Tang Dynasty did not have a so-called national flag.
"National flag?"
"I've never heard of it, and I've never seen it."
