In ancient times, people had relatively shallow contact with chemistry, and there were relatively few people, and most people did not understand it, and those who did not understand it thought it was more mysterious and would not find it interesting. And some alchemists in ancient times also relied on this to make a living, because they understood the psychology of most people, so they used some small knowledge to fool people.
The current chemistry course is a course, there are a lot of foundations to master, and there are few encounters with experiments in places where the conditions are not good, and there are few special discoveries in the process of experiments, and there is not much novelty when the results are known.
Learning courses and interests don't necessarily fit well, but you need to learn it first.

Because the ancients knew so little, it was quite accomplished to discover a few tricks.
But it's definitely not that the ancients are dumber than the modern people, because without the accumulated experience of the ancients, modern people would never have been able to discover and invent so many things at once.
Sitting on the wisdom of the ancients, I don't know how to be grateful but I think that the people of today are smarter than the ancients, I am sorry for my ancestors!

The times have progressed, your ideas have improved, you know more things, and some new inventions can no longer satisfy your eyes, so you are not satisfied with them.
Actually, chemistry is also very fun now.
Have fun finding modern chemistry!
-
Because modern people are dumber than ancient people, or modern people are smarter than ancient people.
-
It's all known, and there's no sense of novelty or accomplishment.

Ancient Chinese science and technology focused on practicality, lacked systematization and rigor, and simply summarized and did not explore the trend of the essence of science, and the same is true of chemistry as a kind of science.
-
Because the Chinese way of thinking is biased towards empiricism and abstract thinking, they do not like to quantify things, and they look down on doing practical work.
-
Because in ancient times, it was explained in ancient texts, so there were civil officials and military generals, and civil officials were on paper in the eyes of military generals! The generals rely on martial arts, if it weren't for the emperor's immortality, those so-called Taoist priests would not have practiced gunpowder! So there's no such concept!

Of course, it's better than in ancient times, in modern times, you at least have the leisure to think about this kind of problem, in ancient times, you didn't have the extra energy to think about this kind of boring thing, in order to be able to eat enough every day, it was enough for you to be physically and mentally exhausted.
Although it is not completely impossible to have such idlers in ancient times, those who are all rich and noble people, in modern times, must at least have a family property of tens of millions, and they are not ordinary civilians at all.
Now some people think that the ancient life is good, and they only refer to the living conditions of the ancient magnates, not the general living conditions of the ancient people.
To put it bluntly, what they envy is not the ancient life, but the life of the powerful, which is not the same thing at all.
To put it mildly, the advantages of ancient life they listed, in fact, the modern elite have the same conditions to enjoy, as long as there is money, pollution-free areas, pure natural food, and even hugging left and right, which one cannot be achieved in modern society? Can it all be done? And it can be achieved better than in ancient times.
But if you don't have money, even if you are in ancient times, you can't enjoy these advantages, there is no chemically polluted air, but you can't escape the garbage and feces and urine everywhere; There are no ripening produce, but you have to eat gruel full of worms and sand; There's no limit to the number of women you can beg, but you have to have the money to support them.
You have no money and no power, you can't enjoy anything in ancient times, and even the living conditions are worse than in modern times, at least in modern times you still have pension insurance, there was no such thing in ancient times.

Each has its own standard, and the standard of living is better now, but the ancient air culture is better than it is now. It can't be any better, it's all reality, in ancient times it could be a slave or a general, and in modern times it is an ordinary person at the lowest level, and it won't hurt.

This, if it is good, the folk customs are more simple, and if it is bad, life is harder.

Chemistry originated from ancient alchemy and medicine, and some of them were produced by medical needs.

The historical origin of chemistry is very ancient, and it can be said that the earliest chemical practice began when humans learned to use fire. Our ancestors drilled wood to make fire, used fire to bake food, kept warm on cold nights, drove away wild beasts, and made full use of the glow and heat phenomenon when burning. At the time, it was just an accumulation of experience.
The formation of chemical knowledge and the development of chemistry have gone through a long and tortuous road. It develops along with the progress of human society and is the inevitable result of social development. And its development promotes the development of productive forces and the progress of history.

That's not what beginners understand. Actual chemistry is the regular activity of molecules or atoms according to a certain standard ratio. It's just that there are some units that you are not familiar with yet.
The decline of a certain genre is related to its living environment. In other words, the linguistic environment has changed, not only the pronunciation has changed, but more importantly, the pronunciation on which these genres rely has changed. It must be known that Chinese rhymes (poems, lyrics, songs, etc.) are all composed for singing, and the ** on which the poem rests is 84 tones; The ** on which the lyrics and music are based is 28 tones (due to the fact that the main instrument is the pipa, the four strings). >>>More

There are many animation adaptations, which are more troublesome to make than comics, and they are dynamic, and all of them need to be reduced; Comics are more original, mainly reflecting the author's painting style and technology, so the author must carefully craft it from the beginning, so as to maintain the quality of the original comics. Therefore, manga is more detailed and delicate than anime.
I think there are several reasons why Hanfu has big sleeves, one may be because ancient people liked to put things in their sleeves, so they can be loaded with things. Second, the sleeves can be said to be a symbol of aristocratic power, and the commoners are mostly narrow sleeves, which is convenient for labor, and in our modern times, the main reason is to make the Hanfu more age and characteristics, so the wide sleeves are retained, which looks more elegant and good-looking.
