There was once a book, The Secret Symphony of Han Miscellaneous Matters, which recorded the criteria for choosing concubines by Herry Liu, the Emperor of the Han Dynasty. A woman remembers the size of every part very clearly-from top to bottom, seven feet and one inch long; The shoulder width is one foot six inches, and the hip and shoulder width are reduced by three inches; From shoulder to finger, it is two feet and seven inches long, and from finger to palm, four inches. Small stone pillars are sprouting. The moustache is three feet two inches long and the feet are eight inches long; The shin is beautiful, the bottom is flat and refers to the convergence, the socks are forced, and the bundle is as small as forbidden, so it can't be long. ..... no hemorrhoids, no choice, no spots, no armpits, no feet. This can be said to be the highest standard of mate selection at that time. Probably only the emperor Lao Tzu has this privilege. Imagine how many people can choose a woman with such a standard figure as a partner? And the woman must have no acne, bad breath, rhinitis, bromhidrosis, hemorrhoids, itching and beriberi. Naturally, there are folk methods, as simple as eight words-fine eyes, red lips and white teeth. This stems from the requirements of ancient house art for mate selection, which seems simple, but in fact it is painstaking. First of all, eyebrows, all women with eyebrows are considered to have poor sexual intercourse skills, lack of shy posture, and are not favored by men. Women with eyebrows on both sides are weak in persistence and neurotic. In addition to the eight-character eyebrows, only women with thick eyebrows like the way of yin and yang handover best, and her sex skills will intoxicate men. This kind of woman's eyebrows are called "clear eyebrows". If the pupil is tilted upward, it will make women fascinated and men fascinated. This kind of woman is called "Muxiu". Women whose pupils are biased towards the lower part of the eyes will make men weak and disgusting. Just be vigilant. Women with red or purple lips are prone to heart paralysis. Only red lips are the symbol of healthy women. This kind of woman's lips are called "red lips". A woman with white teeth can be described as full of yang, and the relationship between teeth and kidneys is deep. People with bad teeth often can't overdo ML because they are weak and sick. Li Yu, a great talent, calmly pointed out in the book * * * *, which is known as the world's first romance novel, that a man's favorite woman is ordinary and fresh, which requires him to be proficient in sex. He told a story-a woman named Hua Chen once gave Weiyangsheng a true biography: "Read first, then take the path of Yin and Yang, and listen to the sound while reading." However, after reading several pictures and books, it was useless. You should prepare hundreds of books, or hundreds of books. You should read a book first. Should not enter the realm of yin and yang soon, only when very excited. In this state of going in and out, I read books and listen to each other. Don't start exercising until you are excited. However, it is not good to continue like this. It is necessary to pause for a moment and let the penis still be in the vulva. Read it again. In addition, hearing the sound again means listening to a person's voice. Of course, it means listening to that person's voice on the Yin and Yang Road, or it can be done by a single person. Huachen asked the maid to use props alone and perform in this way. Reading while having sex is not because you are eager to learn, but to stimulate the sensory enjoyment of your eyes. And listening to the sound is undoubtedly irritating to the ear. There are exceptions to everything in the house of Yin and Yang. In terms of taking a wife and concubinage, in addition to reproduction, of course, pure sexual purpose is not ruled out. The tolerance of concubinage in ancient China met the sexual needs of some people with super sexual ability. Bai Xingjian, the younger brother of Bai Juyi, a great poet in the Tang Dynasty, once wrote an epic poem "On the Joy of Yin and Yang in Heaven and Earth". Tens of thousands of words are eloquent, and the benefits of sex are exhausted. Until today, it still has very important guiding significance. In Fu, common sayings at that time were adopted, such as "containing milk and vinegar" and "sister and brother", which have been used ever since. This Fu is a rare masterpiece of sex literature. The beginning of this poem reads: "The living is the foundation of human beings; Addicts are good for people. Nothing can save money and make money more than food and clothing. "Food and clothing" is enough, not fun. "Pleasure" is the essence, which is very close to the way of husband and wife and accords with the love between men and women. As far as we know, there was no handover. It is also a fact that the rest of the official titles are famous and human feelings are declining. "Bai Xingjian's sexual declaration-life is the most precious, and desire is the need of human survival. An important factor to maintain life is food and clothing. After food and clothing are satisfied, there are still desires and demands such as fame and fortune, but these requirements are insignificant compared with the happiness of husband and wife's sexual life. The universe and nature perfectly and strangely arranged the existence of all things. The connection between heaven and earth (referring to the intersection of yin and yang), the movement and balance of the sun and the moon are ingenious combinations of the biological world. After that, he began to write from the wedding night, writing about sexual life all year round, writing about many gestures and every detail of sex, which is extremely erotic literature from today's perspective. The most terrible thing is the description of "derailment". Ha ha! It is disobedient to live together in a room without marriage and be a stranger. I can't sleep in a hotel, but I stay in a boudoir and live apart. As we all know, beauty and beauty, every sincerity; Seeing the beauty of horses often reminds me of pets. I envy the feelings of the Committee members, and I am willing to throw fruit at spring. It is often madness to think of masculinity; I feel energetic and thin. It is useless to sleep and eat, and there is no exercise. In my dream, I saw it recruiting alone in the dark. The information is thicker than Baidu, and Gu Xi has passed. Thinking about beauty, thinking about slim waist, sometimes coincides with mine, and the soul disappears. ..... or because of something, don't make the bed; Or the grass by the wall, the depths of the flowers. I'm afraid people will know, so I'll be polite Or spread a skirt against the grass, or against the column. Heart and gallbladder are frightened, mental fear. I slept in Sheng 'an when I was in a hurry. This passage can be used as a powerful refutation of China's ancient sex "only reproductive teleology". If it's just to have children, why think about the beauty next door to the hotel? Why toss and turn? Why are you crazy about it? Why do you ask people to match in your dreams? Even having sex with a beautiful woman in a dream makes you dumbfounded and deeply grieved? When it is really "a wife is not as good as a concubine, and a concubine is not as good as a thief." "Although cheating is happy, there are still worries and fears in my heart. Some men and women have casual sexual relations and have no beds. Afraid that others will find out, they will act hastily in corners, lawns and places with deep vegetation, or spread skirts or put some grass under them; Or bend down and insert it from behind, or stand against a post and have sex. Although there are some fears and discomfort, this kind of tryst and sex is a hundred times better than in bed. This strange article also mentioned a kind of sexual health preservation method of the ancients-brain tonic. That is to say, when the climax comes, sometimes you deliberately don't ejaculate, let the semen turn around without leaking, and then you inhale deeply and swallow the body fluids in your mouth. It is said that this method can prolong life and preserve health. Recently, a doctor pointed out that the so-called nourishing yin and nourishing the brain is only speculation of the ancients and has no scientific basis. Moreover, this practice can easily lead to prostatitis and make people lose sexual function prematurely. Unfortunately, this statement has been unable to inform the ancients.
