The atrioventricular health care must abide by the rule of "combination of men and women". According to the documents unearthed in Mawangdui, The Treatise on the World Prescription, which was called China's "sexual classic" 2 100 years ago, emphasized the importance of sexual health care with the world prescription. According to the development law of yin and yang in heaven and earth, this paper discusses how to nourish yin and benefit qi, especially "seven kinds of harmful sexual behaviors and eight kinds of beneficial sexual behaviors". Repeatedly stressed the need to "use eight benefits and divide seven losses." If we can't do this, people's physiological functions will be halved when they live to 40, and their manners will be senile when they are 50. At the age of 60, their audio-visual function will decline. At the age of 70, their lower body will dry up, their upper body will collapse, their reproductive function will be lost, and their tears and noses will flow out together. What is the seven losses? The book says, "Penile pain during sexual intercourse is called adduction; Sweating during sexual intercourse calls away the essence; Excessive sexual intercourse is called semen exhaustion; When it comes to sexual intercourse, it is called impotence; Breathing and irritability during sexual intercourse are annoying; It is amazing that the woman asks for asexuality and the man forces it, which is harmful to her body and mind; Sexual intercourse is too fast and too fast, which is a waste of energy and money. " These are the seven major losses. How can we maintain vigorous sexual function? These eight benefits are rules. The book puts forward: "Get up in the morning to meditate, straighten your spine, relax your hips, converge your anus, and guide your qi downward. This is called treating qi; Swallow body fluid, sit up straight on your hips, straighten your spine, converge your anus, guide qi downward, and dredge its essence, which is called foaming; Both men and women have pleasure after playing first, and sexual intercourse after sexual desire is full, which is called knowing when; During sexual intercourse, relax the back, converge the anus and guide the downward flow of qi, which is called gas storage; Don't make love too fast, but be gentle when pumping. This is called harmony. Sitting up from the bed, when the penis can still erect, it will soon leave the handover, which is called gas accumulation; At the end of sexual intercourse, holding your breath and running on your back, standing still, attracting the weather, guiding your breath downward and waiting quietly, this is called equal victory; After sexual intercourse, sprinkle the residual essence, clean the genitals, and resolutely leave when the penis can still erect. This is the so-called fixed inclination. With these eight benefits, mature people will not get old, and the elderly will regain their health. This will be full of blood, flexible and light, and live happily. " Attachment: The original text of "The World Returns to the Tao" says: "Qi has eight benefits, and there are (and) seven grandchildren (loss). Can't use eight benefits, lose seven grandchildren (loss), 40-year-old Yin Qi and a half, 50-year-old daily life declines, 60-year-old eyes and ears are not bright, 70-year-old is dry, Yin Qi doesn't need it, crying. " "Seven grandchildren (lost): suffering from it, combining it; Sweating for it, leaking it; I was so excited about it that I was exhausted; Qin (Zhen) can't do whatever he wants and take it; Breathing for it is annoying; If you want to be strong, you must be absolute; For Qin (Zhen) disease, it costs money. This is called seven grandchildren (loss). " "Treating eight benefits: sit up, straighten your spine, open your mouth, squat down, seal (suppress) qi, and treat qi; Diet, squatting, straightening the spine, embarrassing state, ventilation, and treating foam; Play two pleasures first, pay attention to it and be wise (know); For the ridge, for the state, for suppression, for gas storage; For things (don't), don't count, go in and out, just talk. Getting out of bed makes people get up, and anger is selected (released), which is called gas accumulation; Several times, inside the spine, motionless, holding your breath, holding your breath, motionless, waiting to win; If you spill it, you will give up in a rage and you will fall down. This stomach will win eight times. Supplementing qi with eight benefits is the reason why the old are rejuvenated, the strong are immortal, full of qi and blood, and light in body. Gentlemen live in peace. " The above is the famous "seven losses and eight benefits" theory. Which is the basic rule for men and women.
