In fact, this idiom is called "female seven male eight", from the "Yellow Emperor Neijing Su Qing", because in the beginning of the "Yellow Emperor Neijing", so it can be seen as the first idiom extended from the "Yellow Emperor Neijing".
Regarding the interpretation of this word, it is actually about the problem of the physiological cycle of men and women, women take seven years as a cycle, produce a change, while men take eight years as a cycle. Today we will take the female seventh as an example to talk about this natural law.
According to the Yellow Emperor's Inner Classic:
[The woman is seven years old.] Kidney qi, longer teeth】
Girls start changing their teeth and long hair at the age of seven;
【Twenty-seven and heavenly decay, Ren pulse, Tai Chong pulse sheng, menstrual events to the present, so there are children】
Fourteen years of age to menstruation, began to have fertility;
【Three seven, kidney qi average, so the real teeth are born and grow pole;】
Twenty-one years of age to the peak of development, this stage is also the development of female secondary sexual characteristics;
【Four seven, strong bones, long hair, strong body】
Twenty-eight years old, physical condition reached the top;
【May 7, Yang Ming pulse decline, face began to scorch, began to fall; (35 years old)
67, the three Yang pulses are decayed on the top, the face is scorched, and the beginning is white; (42 years old)
Seven seven, Ren pulse is weak, too Chong pulse is weak, the sky is exhausted, the tunnel is not clear, so the shape is bad and childless. 】
After the age of twenty-eight, the body enters a period of decay, and at the age of 7749, there is a gradual decrease in hormones and amenorrhea, that is, menopause. The woman then enters old age.
This is the whole process of a girl from development to decay.
And the practice we mention in our daily life is to make our physiological cycle longer, the physiological period longer, and the time you can maintain youth will also become longer, and at the same time, the life expectancy will also be extended. That is, precocious puberty, that is, premature aging.
And what is our situation now? Girls come to menstruation at the age of ten and eleven, and some even come to menstruation at the age of eight. What does this mean? Your cycle changes from seven to five or even four, and then your menopause will come in your thirties and then into old age.
Why do today's children generally have the problem of precocious puberty? The core reason for this is diet.
The intake of a large amount of junk food, various fried foods, hamburger fries, beverage juices, prepackaged snacks, out-of-season fruits, and insufficient exercise can lead to premature puberty in children.
Therefore, for the sake of children, but also for themselves, in addition to strengthening exercise, you should also pay attention not to ingest these junk foods, drinks, etc.
