Chapter 20: Understanding the Way and Applying it

Su You shook his head.

Mrs. Cheng smiled and said: "This is the extremely fine powder that my father extracted using the flying water method according to your method. This is realgar, this is cinnabar, this is pearl..."

After saying that, he dipped his hand into a little pearl powder, put it on the back of his hand, and the pearl powder penetrated into the pores, and said, "Look, how delicate it is."

Su You was surprised and said: "Three thousand eyes!"

Mrs. Cheng was slightly stunned: "Xiaoyou, what do you mean?"

Su You quickly said: "Sister-in-law, it's like this. I once thought about how to classify the particles of matter according to their thickness."

"The particles are all sifted out through a sieve. The coarser the sieve, the coarser the particles will be sifted out, and the finer the sieve, the finer the particles will be sifted out."

"The sieve is actually composed of longitude and latitude lines. I use one inch in length and width, three warps and three latitudes, to get a word "tian", and the four holes in the middle are the four meshes."

"Similarly, four longitudes and four latitudes are nine eyes."

"By analogy, the denser the longitude and latitude lines, the greater the number of meshes per unit area, and the finer the holes."

"I tried to measure the thickness of the skin pores, and finally calculated the fineness of the pores, which should be above 3,000 mesh."

Mrs. Cheng felt a little dizzy after hearing this: "Why are you calculating this when you have nothing to do?"

Su You was speechless and could only touch his nose in embarrassment: "Well... I am too bored."

Mrs. Cheng sighed and said: "Like Zizhan, he has a lot of intelligence and has many interests and hobbies besides classics. This is a good thing. Xiaoyou, if you like this knowledge, you can study it in detail."

"This knowledge is actually extraordinary. The so-called "knowledge and application" is what mediocre people are obsessed with. I hope that you can go hand in hand, enlighten each other, and combine the two. This is the right path, and it will definitely benefit the world."

Su You was greatly impressed by Mrs. Cheng. She was the first person in the world to highly affirm his actions. This kind of magnanimity and magnanimity were something that few parents in later generations could achieve.

He quickly bowed and saluted: "I will definitely live up to my sister-in-law's teachings."

Mrs. Cheng smiled and said: "You don't have to be so restrained. Zizhan Ziyou is very casual in front of me. You can say whatever you want. My sister-in-law will always listen carefully to what the children say."

When Su Baniang was alone with Su You, she always tried to persuade him, but now she said good things to Su You: "Uncle Yao is very good, and he helped me a lot this time."

Mrs. Cheng turned to Banniang and said, "I haven't told you yet, do you know where I went wrong this time?"

Su Baniang felt a little embarrassed and stuck out her tongue secretly: "Mom, Banniang shouldn't act like a fool and think things too simply."

Mrs. Cheng sighed and said: "This is certainly one of the faults, but it is not the most important. Your biggest fault is that you hid it from your grandpa, your son-in-law, and even your parents. Do you know the consequences of doing this?"

Su Banniang lowered her head sadly and said, "Banniang is unfilial and makes her parents worry."

Mrs. Cheng sighed and shook her head: "Not only that, when the matter has reached this point, you didn't tell your family that you were suddenly ill. Do you know what direction it will develop if something happens and everyone on both sides is kept in the dark?"

"With your father's temperament, he will definitely think that you were treated harshly by the Cheng family. This will cause estrangement between the two families and even turmoil in Meishan City. Have you ever thought about this?"

Only then did Banniang become frightened: "Banniang knows that I was wrong. My child really has never thought of this."

Su You admired Mrs. Cheng's knowledge even more. Mrs. Cheng's inference about the follow-up was not right but not far off. Mingrui was like a husband in a boudoir.

In the blink of an eye, Mrs. Cheng mentioned herself and said: "In the future, I will learn more about small things and think carefully about everything, and then I can act." "Fortunately, you are also great. I have also read the regulations of movable type, and they are very good."

It’s impressive, I’m sure it’s between 70% and 80%.”

Su You quickly said: "Sister-in-law, I will definitely do my best to help Ba Niang succeed."

After thinking about how to organize the language, Su You continued: "I have thought about it, even if it doesn't work out in the end, we have a lot more technologies. Such as calipers, such as flour milling, such as coarse and fine classification, these things are not just for movable type printing.

it works."

Mrs. Cheng smiled at Ba Niang and said, "Did you see that? Xiaoyou, this is what a husband should do. He has a broad vision and draws inferences from one case to another."

After speaking, he pointed to the powder in the box and said: "Take powder making as an example. In addition to refining mud and making medicine, you can also mix gouache, makeup honey, and even make ink, right?"

Su You smiled and said: "Sister-in-law clearly sees that in fact, every small breakthrough in technology will bring about progress in various industries, and it is not limited to one corner. But what I just thought of, I went to eat it."

Mrs. Cheng smiled: "I haven't thanked you for the two dishes you brought me at noon. This matter is related to the reputation of the Su and Shi families. You must do it well."

The two agreed, and Mrs. Cheng asked: "Tell me, how are flour making and eating related?"

Su You said: "The water flying method actually uses water as a medium to separate the particles of objects into coarse and fine particles. However, if I think about it carefully, the material that can be used as a medium, besides water, can also be wind."

Mrs. Cheng became a little curious and asked doubtfully: "Oh?"

Su You flashed his hand lightly, and in the light beam of the setting sun in the room, countless dust flew up and disturbed: "Sister-in-law, look, if there is a box with powder at the bottom, keep rolling it, and then blow the wind in from the air outlet, lightly

The powder will be blown up high, and an air outlet will be connected from a high place. The particles will be extracted and collected on the filter, and extremely fine dry powder will be obtained. Substances that will change when exposed to water can be separated by this method.

Get fine powder."

Mrs. Cheng smiled and nodded: "It's really natural. Wait, what do you want to do with this thing?"

Su You licked his lips: "I just want to know what the cakes made from such wheat flour will taste like?"

Both Mrs. Cheng and Ba Niang couldn't help but laugh. Mrs. Cheng smiled and said: "It seems that I am hungry. Ba Niang, go tell the kitchen to get some snacks."

After Su You thanked you, Mrs. Cheng said: "Xiaoyou, things in this world are easier said than done. Banniang has already suffered the hardships. You are extremely smart and can't handle ordinary things, but there are also the same hardships waiting for you."

.”

Su You said: "What my sister-in-law said is the sage's scripture?"

Mrs. Cheng said: "With your understanding, Xiaoyou, the meaning of classics is the least of my sister-in-law's worries. What I'm worried about is the other science of rhyme."

"Your plan for movable type is very clear and feasible. The only exception is the coding, which is based on radical codes."

Su You was puzzled. The dictionaries of later generations included not only pinyin but also radicals, which were very useful.

However, the ancients have their own wisdom, so Su You bowed to Mrs. Cheng and said: "Please give me some advice, sister-in-law."

Mrs. Cheng smiled and said: "It's actually very simple. I have more than 50,000 Chinese characters in the Song Dynasty. If I look for characters by radicals, there are too many characters for each radical."

"Switching to the rhyme part, there are more than two hundred rhymes, so the arrangement is more reasonable."

Su You suddenly realized that the number of commonly used Chinese characters in later generations was only a few thousand, which was incomparable with today's literati. Many Chinese characters, such as Han, Han, and Handan, were almost just words.

But nowadays, they are among the commonly used words, and each word may not be used commonly.

Seeing that Su You had understood, Mrs. Cheng smiled and said: "Sure enough, a little bit will reveal it. Xiaoyou, you must remember that poetry and poetry are the threshold for the imperial court to recruit scholars; rhyme is also the threshold for poetry and poetry."

"When taking the exam, the eight rhymes must not only be mixed within the rhymes, but also the order of the rhymes must not be reversed. If you go out of line even a little bit, you will be deposed."

Seeing that Su You's face turned a little pale, Mrs. Cheng smiled and said: "Xiao You, don't worry too much. I, Wenzong of Xishu, inherited the studies of Sima and Yang Xiong, and started from Han Fu Zhang Ci. Therefore, I am a scholar of Xichuan in the study of rhyme.

With your strong points, you can take advantage of them a lot when taking exams.”

Su You still felt a little cold in his heart. As a lover of classical literature, even if he read a bunch of vertically formatted books in later generations and knew traditional Chinese characters, he could only master 10,000 flexibly.

There are so many, which are far beyond ordinary modern people.

But it is still four or five times worse than the level of 50,000 words.
