Wu Youxing believes that living objects are called living things, and living naturally refers to being able to exchange materials with the outside world and have the ability to reproduce offspring.

He pointed out that through the observation of the human body, animal body, and plant body under the microscope, it was found that all living things are made up of a very small structure, which His Majesty the Emperor named the cell.

Cells in different organisms have some common structures, such as the outermost cell membrane, the inner cytoplasm, and the innermost nucleus. The efficacy of these structures is not yet known, but in living cells, it can be seen that the cytoplasm is not in a quiescent state.

If you look at hair and nails, you can see that the cytoplasm of the cells is not moving, so you can basically assume that they are dead cells.

Finally, Wu Youxing called on all colleagues who are interested in the study of objects to discuss the problems related to biology and disease, and whether the pioneers of device research can further increase the magnification of the microscope, so that everyone can understand the fine structure of cells more clearly.

In the editor's note of this article, it is stated that the Ordnance Bureau can now sell microscopes that can magnify 100 times, with instructions for use, and the price of one is 500 yuan, and everyone is welcome to order it from the agricultural cooperative. "Daming Science Daily" was originally a newspaper edited by Mao Yuanyi of the Ordnance Bureau, and of course this advertisement was to be struck. However, the price is as high as 500 yuan, I believe that only a very small number of people can afford it, and it just so happens that the inventory of the Ordnance Bureau is not much, and after supplying it to the Jingshi University Hall, there are less than 100 units left.

The Daming Weekly also published Wu Youxing's research results in the form of news. And in the article, it is proposed that what should we correctly understand the sage's statement that "the body is skinned, and the parents who receive it must not be damaged, and the beginning of filial piety is also"?

Of course, the weekly newspaper only raised a question and did not discuss it in depth, and Mr. Xiaoqi's article appeared in the next issue of the weekly newspaper (which is now published every seven days) in a letter from readers. Mr. Xiao Qi believes that the meaning of the sage when he said this sentence is, first of all, to ask us to take care of our bodies. It is not easy for our parents to raise us, and if we destroy our bodies at will, it is unfilial. For example, in ordinary life, it is unfilial to injure one's hands, feet or other parts, or even lead to the loss of life, so as to make parents worry and sad.

Secondly, we should know that there are exceptions to this sentence. For example, for the sake of national righteousness, for the safety of the country, and for the sake of the villagers...... At this time, the sacrificial sacrifice is commendable, and it will not be classified as unfilial piety, but will be considered as great filial piety.

If there is a person whose hands are frostbitten and necrotic because of the severe cold. If the injured hand is left unattended, the necrotic injured hand can 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, so is this unfilial piety?

No, because the injured hand is no longer a needed part of his body, and the cells in it have died, not only can not help his body, but have become the culprit of the necrosis of his physical parts. Cutting off the harmful parts and preserving the useful parts should be considered filial piety. So since hair is also a dead cell, cutting off part of your own hair is not unfilial.

So what if we shave off all sides of our hair like the Jurchens, leaving only a ridiculous pigtail? No way! Because we are a people who speak etiquette, we are not barbarians. We can't put on our left side. The hair is long, you think it's very flowing, you think it's comfortable to put on a hosta, and it's powerful to put on a hat, then of course there's no problem. But if you find your hair too long, too hard to wash, or too hot in the summer, then you can cut your hair shorter, which is not a problem.

He concluded: We have to follow the words of the saints, but understand that the times are progressing, and some things are very different from the times in which the saints lived. What we have to comprehend is his profound righteousness, and we should not be entangled in specific cases. Just like this sentence, the point is that we must protect our bodies from damage and respect our lives, but sacrificing our lives for righteousness is filial piety, breaking our arms to survive is also filial piety, cutting off our nails to make it easier to work is filial piety, and shaving our hair short to make it cool in summer is not filial piety!

Next to Mr. Xiaoqi's article, there is also an article that holds the opposite view of him, the author is named Cheng Grace, he believes that the words of the sage cannot be changed by a word, since the sage is talking about the body hair and skin, then the hair should be counted in it. And even if it's a fingernail, you can't just cut it off, because it's also part of the body.

Of course, it is really rare for an opponent to assist in this way, and many people originally had some complaints about some of the points in Mr. Xiaoqi's article, but after reading the article of the benefactor, I feel that Mr. Xiaoqi is more reasonable than the two.

According to statistics, five adults agree with Mr. Xiao Qi's view, two percent agree with the views of the benevolent, and three percent fiercely criticize Mr. Xiao Qi's views, believing that shaving his hair short is tantamount to wearing his hair to the left, and is a symbol of the Chinese civilization being conquered by barbarians.

Zhu Youxiao instructed Wang Chengen to select a representative article of various views, and then publish it in the weekly newspaper, and he wrote an article in the name of Mr. Xiaoqi, pointing out that he did not want everyone to cut their hair short, but only showed that everyone has the right to deal with their own hair, because the treatment of hair does not involve the question of filial piety or unfilial piety. It's just that in the traditional Chinese culture, there is a difference between life and death, and wearing the left side of the hair is the costume of the dead, so it is still recommended that even if you cut your hair short, it is still necessary to tie up your hair, but it is not appropriate for men's hair to be braided, such a person, when walking as a slave and beaten, 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 short to the point where you can't tie it, then as long as you're not afraid that others will treat you as a monk, there's actually no problem. Of course, when dealing with your own hair, you should consult with your parents and listen to their helpful advice. If you insist on seeing what you have seen despite the dissuasion of your parents, you are suspected of unfilial piety. Parents should also understand their children's legitimate demands, and should not completely ignore their children's thoughts just because they respect them, and this is true for hair and other issues.
