**Sexual intercourse during the Hai hour (9-11 PM) is the best time for conception.**

The Chinese poetically describe this time as "the time of ethereal harmony," referring to life in a state of joyful, warm, and peaceful atmosphere. Traditional Chinese medicine attributes this harmonious state to Lesser Yang, hence the character "亥" (Hai) resembles a man embracing a pregnant woman. Hai hour is a time of Yin-Yang harmony, considered the golden hour for sexual intercourse. It involves the union of male and female bodies to achieve Yin-Yang harmony, reaching a state of "three harmonies in harmony," making it the optimal time for conception. While traditional Chinese medicine emphasizes preserving essence and avoiding excessive sexual activity, harmonious sex, when the body is healthy, can bring physical and mental pleasure, stimulate vitality, and is ultimately beneficial.

Human sexual activity serves both for procreation and as a natural blessing. Harmonious sexual relations not only benefit emotional bonds but also physical and mental health. Since humans belong to nature, they should follow their natural instincts. In addition to paying attention to emotions, frequency, environment, and health conditions during sex, it is also important to seize the optimal time for sexual activity to experience the joy of life and prolong life.

So, what is the best time for sexual activity? Western medicine considers 10:30 PM to be ideal, while traditional Chinese medicine (TCM) believes 10:00 PM is best. Western medicine doesn't provide a clear reason, but TCM's reason, as mentioned above, is to achieve harmony of Yin and Yang. Why half an hour earlier than the Western recommendation? This is because the next two hours (21-30 PM) are when the Gallbladder Meridian is at its peak, a time for deep sleep to nourish Yang. If sexual activity occurs at 10:30 PM, the body may still be in an excited state when the Gallbladder Meridian is at its peak, making it difficult to fall asleep. However, if sexual activity occurs at 10:00 PM, the body will already be in a deep sleep by the start of the next two hours, allowing for the preservation of Yang energy. This reflects a TCM perspective: they don't view problems in isolation, treating only the symptoms, but rather believe that the universe, Yin and Yang, and all things are interconnected and require mutual coordination to achieve harmony. Therefore, there are specific guidelines for when to sleep, eat, and engage in sexual activity; one cannot act arbitrarily, otherwise, it will harm the body.

The essence of sex is the reproductive instinct naturally born of love. Two people in love can only achieve the best sexual experience after heartfelt conversation. In fact, in ancient Chinese health practices, the hour of Xu (7-9 PM) is considered a time for communication, the prelude to sex. Good communication during this time, followed by harmonious sex during the hour of Hai (9-11 PM), brings both physical satisfaction and emotional pleasure. In such a harmonious atmosphere, conception at this time is ideal, arguably the best time for conceiving. Modern life is stressful, and due to various reasons, the proportion of men and women who drink and smoke is high. If both partners are planning to have children, they must quit smoking and limit alcohol consumption, avoid intoxication during sex, and maintain a normal, healthy lifestyle to ensure a healthy baby.

**The Immortal Bone Acupoint: Ignites a Man's Passion**

Modern young men are generally experiencing decreased libido, especially couples with children. Their sex life has decreased from once a week to once every two weeks, or even once a month. Many men experience this sexual fatigue. This is due to factors such as high stress levels, busy work schedules, and complex interpersonal relationships in modern society; it can be considered a "disease of civilization."

However, if this situation continues to escalate, it will inevitably cause problems between the couple. This is not just a problem between the couple; it will also lead to chaos within the family, affect the children, and trigger further issues. Therefore, harmonious sexual relations between spouses play a vital role in family stability and marital happiness.

So how can one enhance libido? Traditional Chinese medicine believes that acupressure on the Xian Gu acupoint is most effective in increasing libido. The Xian Gu acupoint is located 3 centimeters above the coccyx; it can promote the secretion of sex hormones and enhance libido. Acupressure on another acupoint located about 2 centimeters above the Xian Gu acupoint is also very effective in relieving fatigue.

When applying pressure to the Xian Gu acupoint, exhale slowly while pressing firmly for 3 seconds. Repeat this 10 times daily to revitalize your energy.

In addition to these, to enhance libido, one should also make lifestyle changes, such as maintaining a regular diet, eliminating fatigue as early as possible, and maintaining a healthy mood. Taking Jin Kui Shen Qi Wan and Liu Wei Di Huang Wan as supplements may also be beneficial.

Additionally, in some countries, purple represents "sex," and people often use the same color for their bedroom wallpaper, carpets, curtains, and sheets. If a couple has separate bedrooms, they might occasionally change the color of their curtains to alter their living environment, which can also help stimulate the libido center and thus increase libido to some extent.
