Does it make any difference who sleeps on the left and who sleeps on the right?

There is no difference between a couple sleeping on the left and a couple sleeping on the right. People nowadays don't pay attention to these things, as long as they feel convenient and comfortable with each other, and they don't care whether the man is on the left or the woman is on the left. But in ancient times, the custom of couples sleeping was that the man was in the room and the woman was outside, and the woman could not straddle the man. The bed used to be next to it, unlike now. Is the average person on the man's left or on the woman's left? No one counted it. However, according to the culture of China for thousands of years, the proportion of men on the left is relatively large. In our daily life, men are left and women are right, which seems to have penetrated into all aspects of our social life by convention. Go to the public toilet, male left and female right; Wearing a wedding ring, male left and female right; There are also wedding photos, couples attending some ceremonial occasions and so on. Men are often on the left and women are often on the right. If the position is reversed, some people will joke that it violates the custom of "male left and female right". How did this custom come from? According to legend, after Pangu, the ancestor of the Chinese nation, became immortal, his body organs were transformed into the sun, the moon, the stars, the four poles and the five mountains, rivers, lakes and seas and all living things. Although this legend contains mythical elements, it provides reference materials for us to study the Sun God and Moon God in China. According to the calendar of the May Movement Calendar, the sun, moon and Er Shen of the Chinese nation are transformed by Pangu's eyes, and the sun god is transformed by Pangu's left eye. The moon god incarnated as Pangu's right eye, and the folk custom of "male left and female right" came from this. So who is Er Shen, the sun and moon of the Chinese nation? The sun god is Fuxi; Moon God is Nuwa, and both of them are legendary ancient gods. The custom of "male left and female right" is also closely related to the philosophical concept of ancient people. Ancient philosophers in China believed that the two opposites of things and people in the universe were Yin and Yang. Things in nature are size, length, up and down, left and right, and so on. The ancients divided it into big, long, upper and left yang, small, short, lower and right yin. Yang is strong and yin is weak. Men's character, men's violent and strong nature belong to the yang in the left, and women's gentleness belongs to the yin in the right. "Male left and female right" also has practical scientific significance in the application of traditional Chinese medicine. "Male left and female right" refers to the physiological differences between men and women in medicine. In traditional Chinese medicine, a man takes qi in his left hand to divide the pulse, and a woman takes blood in her right hand to divide the pulse. Even if the child is sick, he will observe the handprint and adopt the habit of "male left and female right". This is the origin of "male left and female right". This custom, which has been followed to this day, existed as early as the Warring States period more than two thousand years ago. Of course, whether "male left and female right" can really express the physiological differences between men and women is another question. Men are left and women are right, which is the result of thousands of years of tradition that men are superior to women. From left to right, male first, then female. According to the oriental custom, every time you sign, if you are a husband and wife, you must first write the husband's name and add the wife as a suffix. Unlike in the west, everything pays attention to "ladies first", and even the opening speech is "ladies and gentlemen"
