    Long before it was manufactured as a kilogram weight, every country in the world had its own set of calculation methods for its own weights and measures. Among them, the calculation method in ancient China was to use ten grains of millet.

    Based on the weight of ten grains of millet, one hundred grains of millet with little difference is one baht, and six baht is one zi.

    Šu Zai chose ten grains of rice instead of millet.

    "Since last year's harvest, ten thousand grains of rice were selected, and ten grains were selected. These ten grains were neither big nor small. Based on the weight of ten grains, one baht was based on the number of a hundred grains.  As a benchmark, 1,200 figures were taken from the remaining ten thousand grains, and after repeated weighing, the weight of twelve baht was obtained."

    "Twenty-four baht is worth one tael."

    In the Han Dynasty, one tael was 15.6g, and one baht was 0.65g.

    Yan Zai said so, so with this method, the ancient counting method can be reproduced. This is the calculation method in the Qin and Han Dynasties, which originated from "Guanzi" and "Sun Tzu Suanjing", and was used until the Han Dynasty, so this  The system is still very complete, with equivalent conversion formulas.

    "Sun Tzu Suan Jing" says: "It is said that it starts from the millet, ten millet is one ½t; ten ½t is one baht, twenty-four baht is one tael, and sixteen taels is one catty."

    "Han Shu Lv Li Zhi 1": "One yu¨¨ (yu¨¨) contains 1,200 millets, weighs twelve baht, and two of them are two. Twenty-four baht is two, and sixteen taels is a catty."

    Of course, this system is different from that of later generations.

    As for the matter of importance, the earliest recorded dialogue comes from Shan Mugong and Zhou Jingwang. At that time, Zhou Jingwang wanted to mint big money to increase the value of the currency, and then he was sprayed by Shan Mugong.

    Weights and measures are one thing, at least for a long time, they are inseparable. The weight of currency is equivalent to value, and value creates economy and trade, prospers the market and feeds the country

    Coins are heavy but everything is light, and coins are light but everything is heavy.

    Therefore, the standard of "weighing instruments" must not be set arbitrarily.

    "With this, then you can progress upwards in basic units, I reproduce the role of trade-offs, and improve"

    "With this, the weight of the water in the rain gauge has a corresponding standard, so you can judge the upcoming weather based on the size of the stored water level, whether it is normal torrential rain, continuous drizzle, or  Non-stop rainy season, or natural disasters like floods"

    Yuzai pointed to the scale and said, "Lishou started to make this vessel, but people in the world didn't know its function at that time. 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 Zhuanxu, no one knew how to make it.  device."

    Shaohao doesn't like these things, he is a standard food farming advocate, he doesn't have much interest in scales and metal numbers, and this is why Chi You commented on him at the beginning, when the Yellow Emperor appointed Chi You as the head of the "Six Prime Ministers",  At this time, Chi You hadn't gone out to work on his own, but when he heard that he was going to be Shaohao's teacher, he resigned and flew away overnight.

    Šu Zai said to everyone: "Since Suiren, there has been no one who has governed the world without using the way of weighing weight and weight; since Li Fuxi, there has been no one who has said that he can become a king without using the way of weighing weight and weight."

    "In terms of balance, there are ten grains of rice on the left, but these ten grains carry the people of the whole world. Everything that is beneficial to the people must start from these ten grains of rice."

    These words surprised several Qi refiners, and Chi Songzi was also surprised. Although he knew that Yanzai had always been a little bit capable, good at discovering new things and summarizing the wisdom of the predecessors, he really didn't find that Yanzai actually had this kind of "heart of the world"  " thinking.

    "Why should the teacher be surprised?"

    Seeing Chisongzi's expression, Yan Zai couldn't help saying: "Weights and measures are very important things! In this world, there are weights that are not enough, and there are also things that are light;

    "When we cultivated land, we used to calculate it by steps. Two steps of a person equals one step. However, there is no way to calculate the size of the cultivated land. Lishou did not come up with a conclusion, but we used the number of acres to calculate and stipulated how long it should be.  , how wide"

    "In this way, it is convenient for us to summarize the amount of grain in the farmland, how much grain is in one mu of land, and the other mu of land is planted according to this mu. When counting, there will be no loss and loss. If someone steals it, you can find it at once.  Come out and punish him."

    Several Qi refiners looked at each other in blank dismay, Zhu Rong and Chong Bo were even more stunned.

    A tribal wizard who has thought so many things from one tradeoff

    "It's not bad! To be able to reproduce Lishou's weighing device, he should indeed be a person with extraordinary talents!"

    ?Beimencheng praised, and became more and more happy, from "monitoringEverything he saw in the "device" was far less gratifying than what he asked face to face.

    He suddenly asked: "If you were given a tribe of ten thousand people, what would you do with it?"

    This is a question on a whim, Chi Songzi's eyes moved, and Zhu Rong's eyes also moved.

    However, Yan Zai still replied seriously: "I don't know how to manage it."

    Beimen Cheng was very puzzled.

    Concubine Zai stated the reason:

    "Because you didn't tell me what tribe the 10,000 people belonged to. Is it my own tribe or a tribe that has been integrated? Or are there 5,000 slaves among them? How many northerners, how many southerners, how many easterners, how many  Are there people from the West? Are there people from Yumin? Are there people who hate fire? Are there people who nail spirits? Are there people from Yanchang?"

    "Then are these ten thousand people fleeing or migrating? Are they in the era of the Three Emperors, or in the present world? Are they living in dilapidated mountains, lush forests, or vast expanses of land?  East China Sea?"

    Beimen Cheng was stunned for a long time after listening, and finally apologized to Yan Zai: "It's because I didn't think carefully."

    He laughed smirkly as he spoke, and asked himself in his heart that he had worked with the Yellow Emperor for so long and cultivated his qi for hundreds of years, but in the end, he lost all his skills and calculations.

    However, his question and Yan Zai's answer aroused the interest of two people.

    There is an unknown light in Zhu Rong's eyes, which remains dim, while the light in Chisongzi's eyes is very simple and excited.

    Chisongzi simply felt that it was a pity. Dayi told himself at the beginning not to recommend his concubine, but his apprentice had such a great ability, it would be a big push outside, but such a push could not be pretended, so that Chisongzi  feels awful.

    But Zhu Rong was thinking that the appearance of Yan Zai 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 calculating in his heart, and at the same time frowned slightly.

    This is the meaning of the sour man, not the vinegar tank.

    After all, such a little wizard came out of the barren south. Since he came into the sight of the emperor, and the emperor hadn't told him too much information Now this contact, I realized that it turned out to be an extraordinary person.

    It is indeed quite sour This kind of talent is not in the Central Plains?

    Your grandmother, why!
