The reason why there are 8 men and 7 women is that a woman's life takes 7 as a cycle and reflects growth and change every 7 years; The life cycle of men is eight, that is, there is a growth change every eight years.

Odd numbers are positive numbers, even numbers are negative numbers, and the way of heaven and earth is only yin and yang, and yin and yang are combined into one, regardless. There is yin in the yang, and there is yang in the yin, which are mutually rooted and contradictory.

From two yang and one yin, from two yin and one yang. Gossip three men have more yin than yang, and three women have more yang than yin. If lizhu is a woman, she is comparable to the moon as a man. Therefore, women have a yin body outside and a positive number inside, while men have a yang body outside and a negative number inside.

Brief introduction of male and female cycle

Female:

1, seven years old, is the beginning of a girl's tooth changing period.

"This woman is seven years old, with strong kidneys and longer teeth." Chinese medicine believes that kidney is the foundation of congenital, which can promote human growth and development. When the girl is 7 years old (that is, 6 years old), the kidney qi begins to flourish. Teeth and hair are controlled by the kidneys. So their deciduous teeth began to fall off and grow permanent teeth; Hair will grow longer and thicker, from "girl" to lively and lovely little girl.

2, fourteen years old, to meet the coming of menstruation.

"On the 27 th, the sky is coming, the pulse is connected, the pulse is too strong, and the month is in the present, so there is a son." Tiangui refers to menstruation, while Renmai and Taichong are two meridians in charge of sexual development. A girl with a nominal age 14, with the start of ren meridian, her menstruation came on time and she had the ability to get pregnant and have children. This is why the age of menarche of most girls in China is 13 years old. Of course, plus or minus 2 years old is normal.

At the age of 21, a girl became an adult.

"Sanqi kidney qi is general, so real teeth are born and long." 2 1 year-old, marking the end of girlhood, the body has matured and has the appearance and posture of an adult woman. At this time, the kidneys are particularly rich and stable, and the body is strong, and wisdom teeth will grow. Western medicine also says that the body will reach its peak at the age of 20, and then it will slowly age. It can be seen that 2 1 year is the golden age for women.

4, 28 years old, the best age for childbirth.

"Four or seven bones are strong, the hair is extremely long, and the body is strong." If women are properly maintained, the grand occasion of 2 1 year-old will last until the age of 28. Their bones and muscles are strong, their hair grows to the peak and they are healthy. The birth of the first child at this time will definitely make the mother and child safe.

At the age of 5, 35 and 42, women are aging.

"May 7th Yangming pulse failure, face began to focus, hair began to fall off. The pulse of the six, seven, three yang is failing in the upper part, and the face is white. " A 35-year-old woman, her face began to haggard, wrinkles appeared and her hair lost its luster. White hair began to grow at the age of 42. These physical characteristics indicate the coming of aging.

6, 49 years old, female menopause.

"On July 7, the pulse failed, the pulse failed, the sky was exhausted, and the tunnel was impassable, so the shape was bad and there was no child." The 49-year-old is a woman's menopause. Her pulse is weak, she is too impulsive, her menstruation has stopped, her face is old, and she can't give birth again. Whether you are 45 or 52, your biological age is equal to 49.

Male:

1, an eight-year-old boy with long hair and changed his teeth.

"My husband is eight years old and has strong kidneys and long teeth." Just like girls, boys will change their teeth and grow long hair because of their strong kidney qi. However, boys were born late and started at the age of 8. Eight years old for a boy is equivalent to seven years old for a girl.

2. Sixteen years old, male, at dawn.

"Twenty-eight kidneys are full of qi, the sky is full, the essence overflows, and the yin and yang are harmonious, so you can have children." A man's god is sperm.

At the same time, the voice will be lower and the beard will grow.

You should pay attention to exercise to keep healthy.

"Five kidneys and eight qi are failing, and teeth are falling." 40-year-old middle-aged men are prone to hair loss, yellow teeth and poor sexual desire. These are all caused by deficiency of kidney qi.

5, 48 years old, gaunt and old.

"The sun's qi decays in the upper body, and the face is burnt and gray." At this age, the man's Yuanyang gradually declined and developed in the direction of Yin, so his face was haggard, his hair turned white, he was easily tired, and his physical strength was not as strong as when he was young.
