106 years ago today, on April 15th, 1919 (March 15th, 1919 in the lunar calendar), New Youth advocated public socialization between men and women. On April 15th, 1919, New Youth, Volume 6, No.4, published an article signed by Yang Chaosheng, "Men and Women's Social Openness", advocating "breaking the boundary between men and women and enhancing the personality of men and women". He said in the article, I think men and women are both human beings, and there is no difference between them except that their physiological organization is slightly different. Why do we Chinese people have all kinds of problems because of these two words? Personally, it's all poisoned by the word "etiquette" inherited from the ancients. In ancient times, there was no "etiquette" or "etiquette", and there was no problem between men and women. Since the word "etiquette" came into existence, then men and women have a boundary! There is a ceremony defense! Men's and women's communication is secret! The emotions of men and women have become something that can't be said to others! Isn't it ridiculous that a China with 40 million people has almost become two Chinas with 20 million people? He pointed out that the so-called "courtesy defense" is just a mask to coax people. However, it is strictly defended, and once it is broken, it will be even worse. If men and women had always seen them the same way, there would be no furtive secret behavior. We don't set up "courtesy defense" and see that all human beings are equal. Then, communication is naturally not secret and open, and emotions are not spammed and single-minded! He also said that women are people, not things. Between a man with personality and a woman with personality, communication means communication between people, and it doesn't matter whether "courtesy defense" or "courtesy defense". "Morality" is true, good and beautiful, while "courtesy defense" is false and false. Having "courtesy defense" is not enough to lead to morality. Without "courtesy defense" is not immoral, and it can lead to morality. Therefore, to keep old-fashioned morality, it is also advisable to break the boundary between men and women and make communication open. As for those who talk about maintaining etiquette and polygamy, advise him not to say anything more.
