Long before the one-kilogram weight was manufactured, every country in the world had its own way of calculating weights and measures. Among them, the calculation method in ancient China was to use ten grains of millet.
The weight of ten grains of millet is the basis, one hundred grains of millet with little difference is one baht, and six baht is one 锱.
Yu Zai selected ten grains of rice to replace the millet.
"Since last year's harvest, ten thousand grains of rice have been selected, and ten grains have been selected. These ten grains are neither big nor small. Based on the weight of these ten grains, the number of one hundred grains is one baht, so this is
Then, from the remaining ten thousand grains, we took a number of twelve hundred, and after weighing it repeatedly, we got the weight of twelve baht."
"Twenty-four baht weighs one tael."
In the Han Dynasty, one liang was 15.6g and one baht was 0.65g.
Yu Zai said this, so using this method, the ancient counting method can be reproduced. This is the calculation method of the Qin and Han Dynasties, derived from "Guanzi" and "Sun Zi Suan Jing", and was later used until the Han Dynasty, so this is
The system is still very complete, with equivalent conversion formulas.
"Sun Tzu Suan Jing" says: "The name comes from millet, ten millet is one bamboo, ten bamboo is one baht, twenty-four baht is one tael, sixteen taels is one catty."
"Han Shu·Lü Li Zhi 1": "A yuè contains one thousand and two hundred millet and weighs twelve baht. Two of them are two. Twenty-four baht is two, and sixteen two is a catty."
Of course, this system is different from that of later generations.
As for the importance of matters, the earliest documented exchange of questions comes from Shan Mu Gong and King Zhou Jing. At that time, King Zhou Jing wanted to mint large amounts of money to increase the currency value, and then he was scolded by Shan Mu Gong.
Weights and measures are one thing, at least for a long time, they are inseparable. The weight of currency is equivalent to value. Value creates economy and trade, prospers the market and nurtures the country....
Coins are heavy but everything is light, coins are light but everything is heavy.
Therefore, the standards for "weighing instruments" cannot be set arbitrarily.
"With this, you can proceed upward from the basic unit. I reproduced the effect of trade-offs and improved them..."
"With this, the weight of water in the rain gauge will have a corresponding standard, so we can judge the upcoming weather based on the size of the stored water level, whether it is a normal heavy rain, a continuous drizzle, or a heavy rain.
The non-stop rainy season or natural disasters like floods..."
Yuzai pointed to the scale and said: "Li Shou first made this instrument, but at that time the world did not know its function. At least during the Hao period, the world's center of gravity turned to Dongyi, so it was buried for more than ten years. After Zhuan Xu, no one knew how to make it.
device."
Shaohao didn't like these things. He was a standard grain agriculturist, and he wasn't too interested in metal numbers on scales. This was also the problem with Chi You's evaluation of him. Back then, the Yellow Emperor appointed Chi You as the head of his "six prime ministers".
At this period, Chi You had not yet gone out to work on his own, but as soon as he heard that he was going to be Shaohao's teacher, he resigned and flew away overnight.
Yu Zai said to everyone: "Since the time of the Sui people, there has been no one who has governed the world without using the method of weighing the important and the important; since the time of the Fuxi clan, there has been no one who has become a king without using the method of weighing the important and the important."
"In this balance, there are ten grains of rice on the left, but these ten grains of rice carry the entire people of the world. Everything that is beneficial to the people must start from these ten grains of rice."
These words surprised several qigong masters, and Chi Songzi was also surprised. Although he knew that Ruzai had always been capable and good at discovering new things and summarizing the wisdom of his predecessors, he did not realize that Ruzai actually had this kind of "mind for the world."
"Thinking.
"Why should the teacher be surprised?"
Seeing Chi Songzi's expression, Yu Zai couldn't help but say: "Weights and measures are very important things! In this world, there are things that are not as heavy as a feather, but there are things that are as light as a feather; there are things that are as high as a road, and things that are as far as a candle dragon."
"When we cultivated land, we used to use steps to calculate. Two steps equals one step. But there is no way to calculate how big the cultivated land is. Li Shou did not come up with a conclusion, but we used acres to calculate and stipulated how long it would be.
,how wide...."
"In this way, it is convenient for us to summarize the amount of grains in farmland, how many grains are in one acre of land, and other acres of land are planted according to this acre. When counting, there will be no missing or loss. If someone steals it, we can find it at once
Come out and punish him."
Several Qi refiners looked at each other, Zhu Rong and Chong Bo were even more shocked.
A tribal wizard has thought about so many things from a single perspective...
"That's not bad! Someone who can reproduce Lishou's weighing tool must be someone with extraordinary talent!"
Bei Mencheng praised him and became even more happy. What he saw from the "monitor" was far less joyful than what he saw face to face.
He suddenly asked: "If you were given a tribe of ten thousand people, how would you manage it?"
This was a question made on a whim. Chi Songzi's eyes moved, and Zhu Rong's eyes also moved.
However, Yu Zai still replied seriously: "I don't know how to manage it."
Bei Mencheng was very confused.
Yu Zai gave the reason:
"Because you didn't tell me, what tribe are these ten thousand people? Are they my own tribe or a merged tribe? Or are there five thousand slaves among them? How many northerners, how many southerners, how many easterners, how many
Westerners? Are there any feather people? Are there any fire-weary people? Are there any Nailling people? Are there any Yanchang people?"
"So are these ten thousand people on the way to escape, or on the way to migration? Are they in the era of the Three Emperors, or are they in the current world? Are they living in dilapidated mountains or lush forests, or in the vastness of the world?
East China Sea?"
Beimen Cheng was stunned for a long time after hearing this, and finally apologized to Yu Zai: "I was not thoughtful."
As he spoke, he also started to giggle, and he blamed himself in his mind. He had worked with Huang Di for so long and cultivated Qi for hundreds of years, but in the end, he had lost all his ability and care.
However, his question and Juan Zai's answer aroused the interest of both people.
There was a light of unknown meaning in Zhu Rong's eyes, which remained dim, while the light in Chi Songzi's eyes was of simple excitement.
Chi Songzi simply felt that it was a pity. Emperor Yi had told him not to recommend Yu Zai, but his disciple had such great ability, and if he was put outside, he would be a powerful person, but such a big person could not pretend, so Chi Songzi
feels awful.
Zhu Rong was thinking that Yu Zai's appearance might be one of the reasons why the emperor asked him to come to the south.
"This little wizard is not simple."
Zhu Rong was worried and frowned slightly.
This is because the jealousy is not meant to be jealous.
After all, such a little wizard appeared in the barren south. Now that he has come into the sight of the emperor, and the emperor has not told him too much information... Now that he has this contact, he understands that he is extraordinary.
It’s indeed quite sad... Such talents are not found in the Central Plains region?
