Reflections after reading refers to reading a book, an article, a paragraph, a few famous quotes, a piece of music, and then writing an article based on the feelings and revelations obtained. Below is a sample essay I compiled after reading "Tiangong Kaiwu". I hope it will be helpful to everyone. Comments after reading "Tiangong Kaiwu" Chapter 1
Human survival depends on grains, but the growth of grains requires human planting, and human development requires science and technology. "Tiangong Kaiwu" is a summary of our ancestors' agricultural and industrial technologies. It is the earliest surviving work and is far ahead of the world at the same time. It describes in detail the cultivation of agricultural species and metallurgical processes. At the same time, Research experiences on process equipment and organizational production are also described.
In terms of the cultivation of crop varieties, this book analyzes the impact of soil, climate and cultivation methods on the growth changes of crop varieties through people's research on the development of new varieties such as rice and wheat. The variation that occurs during hybridization points to the ways in which humans can change the characteristics of species. This laid a theoretical foundation for the cultivation of new crop varieties.
In terms of metallurgical technology, it describes the smelting of zinc and the zinc-copper alloy. This is not only the first in Chinese history, but also the first in the history of world science and technology development. The book's method of using zinc metal instead of calamine to smelt metallic copper is also the first record of the use of this technology in world history, which is very precious.
The descriptions of various process technologies in the book, such as the application of waterwheels, steel filling technology, lost wax casting, coal mine gas removal technology and melting technology, all involve many physical mechanics and thermodynamics. aspects of knowledge. "Tiangong Kaiwu" reflects the development level of science and technology in the world at that time to a certain extent.
The description of agriculture and industry in "Tiangong Kaiwu" is admirable, and what surprises me even more is the wisdom of the ancients. "Soil veins vary over the ages, and species characteristics vary with water and soil." This contains philosophical meaning and tells about the changes in things, from soil to crop varieties and characteristics, which will change with the changes in water and soil. I was shocked that the ancients could realize this law of development. Who said that the wisdom of the ancients could not match that of modern people? Isn't this good evidence? After-reading "Tiangong Kaiwu" Chapter 2
"Tiangong Kaiwu" is a comprehensive work on agriculture and handicraft production written by Song Yingxing, a scientist in the Ming Dynasty. It includes agriculture, handicrafts, industry - such as Production technologies such as grain and oil, machinery, bricks and tiles, ceramics, sulfur, candles, paper, weapons, gunpowder, textiles, dyeing, salt making, coal mining, and oil extraction.
With the advancement of science and technology today, many of the advanced knowledge and skills in "Tiangong Kaiwu" in the author's opinion have fallen behind and can no longer be used as process instructions. However, the author's serious and rigorous writing attitude is still worthy of recognition. The knowledge in the book is a valuable legacy left by previous generations, and much of it is still worthy of reference by current people. In particular, the author's viewpoint of "emphasis on the coordination of human beings with nature and the coordination of manpower with natural forces" is even more worthy of our descendants' admiration and attention.
When I read about using clarified yellow mud water to filter out sucrose as white as frost and snow, when I read about the subdivided crop varieties and their knowledge about planting, irrigation, fertilization, harvesting and processing, when I read about those When refining skills such as sericulture, jacquard textiles, printing and dyeing, one has to marvel at the meticulousness and sophistication of the ancients. I shouted, it turned out that our ancestors were so capable!
An ancient Chinese history is not just about the emperors and generals recorded in the official history. They were fighting for power and profit, and the candle shadow was shaking red. There were so many capable people and strangers who did not seek to be prominent and worked quietly at the bottom. , as the foundational pillar of the country, it has supported a huge five-thousand-year legend amidst all the difficulties and dangers! To be clear, those wise kings and ministers who are praised and praised have far more damaging and hindering effects on production and scientific development than promoting them.
"The suede skin is stripped of hair, and cooked with saltpeter to make coats and trousers to protect the wind and toilet, preferably socks and boots... Special foreign objects such as golden monkeys are used as hat covers; they are used to pull the lining of the royal clothes I think the robes are all non-Chinese things. People who wear animal skins have this rough idea, but they cannot be described in detail. Among the birds, there are velvet feathers from the belly of eagles and the flanks of wild goose. If you kill ten thousand animals, you will get a fur coat, which is called velvet. "Use it?"
"The craftsman who makes the flower pattern is the most ingenious. The painter first draws the pattern and color on the paper, and then uses the silk thread to measure the pattern and then knot it. On the hanging flower tower, the weaver didn't know what color to make, threaded the heddle and the warp, and lifted up the stitches according to the exact size. After shuttle, the flowers appeared, and the silk was covered with silk to make the flowers appear light, and the gauze was used to correct the weft. See the flowers. The silk fabrics are lifted in a shuttle, and the gauze is shuttled back and forth. The gods are clever and prepared. "
In the past, I couldn't think of the story of rice harvesting in the south. What does that kind of bucket for beating rice look like?
It wasn't until one day when I saw the illustrations in the book "Tiangong Kaiwu" on the supermarket bookshelf that I realized, "Oh, this is what it is like!"
I used to draw for the architect Liang Sicheng I was amazed by the exquisitely detailed drawings of ancient buildings. When I saw the illustrations in "Tiangong Kaiwu", I realized that under the conditions of backward science and technology, the ancients' academic spirit was far more rigorous than that of today's people. The so-called The masters of the Republic of China are just closer to our era and have more publicity. Throughout the ages, I don’t know how many skilled craftsmen or intellectuals have turned spring mud into spring mud to cultivate the gorgeous and dazzling peony of modern civilization!
I used to regret that precision mechanical drawings weighing several hundred kilograms were treated as waste paper and sent directly to the paper factory for recycling. After watching "Tiangong Kaiwu", I realized that everything in this world is wasted. , not just those drawings! The backward system of recruiting scholars with stereotyped writing is extremely harmful to the country. A talent like Song Yingxing actually failed the five general examinations, and his highest official rank was just a prefect. I was lonely when I was born, and I am still lonely after becoming famous. Until now, I have never seen any TV series or literary works that specifically recommend and praise this scientific spirit.
In the past, Shanxi Qiao Zhiyong was doing business in Hohhot, Inner Mongolia. He competed with others to dominate the market of sesame oil and hoarded a large amount of sesame oil. When the jars and jars were used up, he simply sewed bags with sheepskin, filled them with oil, and loaded them on rafts. Down the river. There is oil leakage on the road, and even the river is floating with oil, which smells delicious. At that time, I thought, this flax oil must not be sesame oil, right? Or another breed? Sesame oil is so expensive, why would you waste it like this?
After reading "Tiangong Kaiwu", I realized that flax is also known as sesame. Today, people have annotations that it is sesame. I heard from a friend that flax is an oil crop in cold northern regions. It is different from sesame and has been seen in northern Shanxi. Flax oil has a slightly pungent taste, which is better than cottonseed oil but nowhere near as good as sesame oil. I think this friend is right, seeing is believing. Whether it's sesame oil or flax oil, this Qiao businessman who connects the world is really willing to spend money to make it!
Our media is happy to report on the dynamics of officials, the secrets of celebrities, the legendary skills of businessmen... A large amount of media resources are wasted on promoting some backward ideas, what the heirs. , palace fights, superstition of gods and ghosts, strange forces and chaos, swords and swords, comparisons of the rich and the poor, fights between mother-in-law and daughter-in-law, mutual harm at the bottom...
If the righteousness is not good, the right way is not clear, and science is not important, use it The advanced Internet spreads all kinds of feudal, superstitious and backward thoughts and behaviors. It does not vigorously promote the rights and obligations of citizens and promotes scientific and democratic development. It just anesthetizes and fools the public with all kinds of vile stuff all day long.
On the popular live broadcast platform, there are not only beauties who can say something, act coquettishly and want rewards, but also a wrinkled fortune teller who wants to join in the fun. He even wears glasses and uses the live broadcast platform. Fortune telling on the spot! In this era, people are really speechless! Knowledge and culture should be used to promote human development and progress, to live in harmony with nature, and to allow a better life to last longer, rather than for luxury and enjoyment and plundering nature's resources for short-term enjoyment.
It is definitely not a good thing to pollute water sources, pollute the air, use various toxic chemicals to increase the production of animals and plants, and rely on overpaying future generations in advance to maintain current living standards. Perhaps, in a few decades, all that will be left are the devastated cement roads, reinforced concrete buildings with broken walls, wild grass and deserted cities, and black water and white sand. The only thing future generations can do is curse, what else can they say! After-reading "Tiangong Kaiwu" Chapter 3
The first time I learned about the book "Tiangong Kaiwu" was on TV. I watched a public welfare film "Classic China" which talked about it. This book is called the Encyclopedia of Chinese Crafts in the 17th Century by scholars. It was these words that caught my eye, so I bought this book two years ago, ready to see the true content of the Encyclopedia of Crafts.
The author is Song Yingxing. This book mainly writes about the five major parts of food, clothing, housing, transportation, and use. This book writes about the classic Chinese technology in the Ming Dynasty at that time.
In the first page of the work, "Nai Li" is written. Through people's research on the development of new varieties of rice, wheat, etc., it analyzes the impact of soil, climate and cultivation methods on the growth changes of crop varieties. At the same time, based on the variation that occurs when silkworms and moths hybridize, it is pointed out that artificial methods can change the characteristics of species. This also laid a theoretical foundation for the cultivation of a new agricultural general.

We must learn first, pay attention to the test of knowledge, and do not make assumptions and talk. There are some people in the world who are smart and knowledgeable, and are highly respected by everyone, but they can't even tell the difference between jujube flowers and pear blossoms, but they guess about Chu Ping. They rarely even touch the molds, but they talk about what Yingding is. Second, we advocate doing things according to rules and not blindly or opportunistically. For example, "Nai Li. Rice Disaster" Segu Sum and Collection Guy must be diligent, but do not do it blindly, otherwise it will cause mildew and affect the germination rate and disease resistance. This is all the author's constant observation and continuous learning. knowledge gained. Third, even if we innovate and develop, we should not be conservative because of conflicts. Fourth, he respects the majority of workers and praises his sincere spirit, attaches great importance to the painstaking use of observation, scientific methods of observation, recording, thinking and consulting literature and research, and finally, with his continuous efforts, he wrote "Tiangong Kai" Objects".
I admire the description of agriculture and industry in "Tiangong Kaiwu", and I am even more surprised by the wisdom of the ancients.
The ancients had already realized the law of development in the Ming Dynasty, which shocked me. Who said that the wisdom of the ancients was not as good as that of modern people? Isn’t this a better testimony?
