Wu Youxing believes that living objects are called living things, and being alive certainly means that they can exchange materials with the outside world and have the ability to reproduce.
He pointed out that through observation of human bodies, animal bodies, and plant bodies under a microscope, he found that all living things are composed of a very small structure, which His Majesty the Emperor named cells.
Cells in different organisms all have some common structures, such as the outermost cell membrane, the inner cytoplasm, and the innermost nucleus.
The function of these structures is not yet known, but in living cells it can be seen that the cytoplasm is not static.
By observing hair, nails, etc., we can find that the cytoplasm of the cells here is immobile, so we can basically conclude that these are dead cells.
Finally, Wu Youxing appealed to colleagues who are interested in the study of objects to discuss issues related to biology and disease.
Can pioneers in device research further increase the magnification of microscopes so that everyone can understand more clearly?
The fine structure of cells.
The editor's note of this article states that the Ordnance Bureau now sells a microscope capable of magnifying 100 times, with instructions for use.
Each unit costs 500 yuan.
Everyone is welcome to order from the agricultural cooperative.
The Ming Science Journal was originally a newspaper edited by Mao Yuanyi of the Ordnance Bureau, so this advertisement was of course necessary.
However, with the price of up to 500 yuan, I believe only a very small number of people can afford it.
It just so happens that the Ordnance Bureau does not have much inventory.
After supplying it to the Capital University, there are less than 100 units left.
The Ming Dynasty Weekly also published Wu Youxing's research results in the form of news.
He also pointed out in the article, what is the correct way for us to understand this passage that the sage said: "The hair and skin of the body are received from the parents and should not be damaged.
This is the beginning of filial piety."
Of course, the weekly newspaper only raised a question and did not conduct an in-depth discussion on the issue.
Mr.
Xiao Qi’s article appeared in the readers’ letters of the next issue of the weekly newspaper, which is now published every seven days.
Mr.
Xiao Qi believes that the saint’s meaning in saying this is first of all to ask us to take care of our bodies.
It is not easy for our parents to raise us.
It would be unfilial to damage our bodies at will.
For example, in daily life, it is unfilial to injure one's hands, feet or other parts, or even cause loss of life, thereby making parents worried and sad.
Secondly, we should know that there are exceptions to this sentence.
For example, for the sake of national justice, the safety of the country, and the sacrifice of one's life for the sake of fellow villagers and elders, it is commendable.
It will not be classified as unfilial, but will be regarded as great filial piety.
If a person has frostbite on his hands due to the severe cold, it will cause necrosis.
If the injured hand is ignored, the necrotic injured hand may cause damage to other parts of his body and eventually death.
So sawing off his injured hand at this time is equivalent to saving his life.
Is this unfilial?
No, because the injured hand is no longer a needed part of his body.
The cells in it are dead.
Not only can they not help his body, but they have become the culprit of necrosis in healthy parts of his body.
Cutting off the harmful parts and preserving the useful parts should be regarded as filial piety.
So since hair is also a dead cell, cutting off part of your hair is not considered unfilial.
So is it okay to shave off the surrounding hair like the Jurchens, leaving only a ridiculous little braid?
No, because we are a nation of etiquette, we are not barbarians.
We cannot wear our left lapels.
If your hair is long and you think it looks elegant, a hosta feels comfortable, or a hat looks powerful, then of course there is no problem.
But if you feel that your hair is too long, difficult to wash, or too hot in summer, then cutting your hair shorter is not actually a problem.
He finally concluded: We must follow the words of the saints, but we must understand that the times are progressing, and some things are very different from the era in which the saints lived.
What we need to understand the sage’s subtle words and great principles is his profound principles, rather than getting hung up on specific examples.

Just like this sentence, the key point is that we should protect our bodies from damage and respect our own lives.
However, sacrificing one's life for righteousness is filial piety.
Cutting off an arm to survive is also filial piety.
Cutting off nails to make it easier to work is filial piety.
Shaving them short Hair keeps you cool in the summer, so why can’t it be a sign of filial piety?
Next to Mr.
Xiao Qi's article, there is also an article that holds the opposite view to him.
The author is named Chengenzhe.
He believes that not a word of the saint's words can be changed.
Since the saint talks about the body, hair and skin, then it must be Count the hair in it.
And even fingernails cannot be cut off casually, because they are also part of the body.
Of course, it is really rare for an opponent to provide assists like this.
Many people originally criticized some of the views in Mr.
Xiao Qi’s article, but after reading Cheng Enzhe’s article, they feel that Mr.
Xiao Qi’s words are more valid.
Makes sense.
In the next issue of letters from readers, according to statistics, 50% of people agreed with Mr.
Xiao Qi’s point of view, 20% agreed with Cheng Enzhi’s point of view, and 30% violently criticized Mr.
Xiao Qi’s point of view, believing that shaving one’s hair short is tantamount to The left-folded hair is a symbol of Chinese civilization being conquered by barbarians.
Zhu Youxiao instructed Wang Chengen to select representative articles from various views and publish them in a weekly newspaper.
He also wrote an article in the name of Mr.
Xiao Qi, pointing out that he did not want everyone to cut their hair short, but just It shows that everyone has the right to deal with their own hair, because the treatment of hair does not involve the issue of filial piety or unfilial piety.
It's just that in traditional Chinese culture, there is a distinction between life and death.
Hair left untied is the attire of the dead.
Therefore, it is still recommended that even if you cut your hair short, it is still necessary to tie it up, but it is not necessary for men to tie their hair into braids.
It is inappropriate for such a person to be beaten as a slave while walking.
I believe that the judge will not punish the beater.
If the judge punishes the beater, we will ask His Majesty the Emperor for pardon.
And if you cut your hair so short that it cannot be tied up, there is actually no problem as long as you are not afraid of others thinking you are a monk.
Of course, when dealing with your own hair, you should discuss it with your parents and follow their helpful opinions.
If you insist on your opinion despite your parents' dissuasion, it would be suspected of being unfilial.
Parents must also understand the legitimate demands of their children.
Just because their children respect them, they cannot completely ignore their children's thoughts.
This is true for hair issues, and the same is true for other issues
