Commonly known as "menstruation" and "regular vacation" by modern people.
This is an ancient term, the phenomenon of women's physiological cycle. Erqi refers to a girl who is fourteen years old. According to Huangdi Neijing, in ancient times, the menarche of girls was about 14 years old, which was also a symbol of girls entering adulthood.
As we know, in ancient times, there was a proverb that a girl refers to a girl of 15 years old, and women must obey their parents' orders and matchmakers' words, and then they can get married with the dowry.

Interpret "Tiankui" (menstruation) from the following aspects
1, menarche age
Menarche is the time of first menstruation, and it is a sign of the beginning of female puberty. The ancients mentioned that "27 years old and the day is coming" means that 14 years old is the time of menarche.
In fact, the menarche time of women is different, mostly between 13- 14 years old, but it may be as early as 1 1 year old or as late as 15 years old. About 2 years before menarche, there may be secondary sexual characteristics such as accelerated growth of height, breast development and pubic hair growth.
2, menopause time
Most women are menopausal between the ages of 45 and 55. Menopause means the loss of female reproductive function. In fact, there was a stage of gradual ovarian decline before menopause.
Therefore, the concept of "perimenopausal period" is now mentioned in medicine, which includes three stages: premenopause, menopause and post-menopause. At this stage, a series of changes can occur, such as menstrual changes, reproductive organ atrophy, mental and neurological symptoms, cardiovascular diseases and osteoporosis.
3, menstrual cycle
The menstrual cycle is from the first day of menstrual cramps to the day before the next menstrual cramps, which is generally 28-30 days.
4, menstrual period
Menstruation refers to the menstrual period of a woman, which is generally 2-8 days, with an average of 4-6 days. Prolongation of menstrual period should first rule out whether there are blood system diseases, organic diseases and the influence of IUD, etc. The main reason for functional menstrual period prolongation is corpus luteum atrophy.
5, menstrual flow
Menstrual volume refers to the amount of menstrual bleeding. Normal women's menstrual blood volume is 20-60 ml, less than 20 ml is oligomenorrhea, and more than 80 ml is menorrhagia.
Too little menstrual flow may cause endometrial lesions or injuries, such as endometrial tuberculosis or endometrial thinning after repeated curettage.
Excessive menstrual flow may be due to uterine fibroids or dysfunctional uterine bleeding, and blood system diseases or long-term use of anticoagulants may also have an impact.
6, menstrual blood characteristics
Normal menstrual blood is generally dark red, light at first, gradually deepened later, and finally turned pale red and clean. The main feature of menstrual blood is that it does not coagulate, and occasionally there are some small clots. If there are a lot of blood clots, you should be alert to the possibility of uterine fibroids.
7, dysmenorrhea
Dysmenorrhea is the most common accompanying symptom of menstruation. Due to hormonal changes or pelvic congestion, many women have abdominal distension, backache or other discomfort before and after menstruation, but they can generally be relieved by rest or after menstruation. However, if there is progressive dysmenorrhea, the possibility of endometriosis or adenomyosis should be considered.
