In China, at least in the Han living area, a woman in labor is treated as a VVIP for about thirty days after giving birth, probably living a happy life of “meals coming from the mouth and clothes coming from the hand” and “shoulders without stretcher and hands without basket”. Whether in the city, or in the countryside, women are enjoying a special treatment called “sitting on the moon”, and some give birth to a baby boy maternity treatment may also be more favorable, like a real queen. Of course, in the modern world, “sitting on the moon” for some people is not necessarily enjoyable, or even suffering. It is said that some maternity during the moon child because of the old man down “cover the moon child” tradition, in the moon was wrapped tightly, prickly heat, heat stroke, and even death from heat stroke. 2017 July 9, Zibo City, Shandong Province, there is a maternity due to “cover the moon child “heatstroke after incurable, so that that newborn baby lost its mother. In addition to the above enjoyment, in fact, sitting in the month of the maternal diet, hygiene, and even habits will be subject to a variety of “puritanical” constraints, said it is not too much to suffer. From a scientific point of view, the long-standing Chinese tradition of “moonlighting” is definitely a bad habit. In modern society, there is no other country or nation in the world that has such a tradition, and even in some European and American countries, a woman can engage in a lot of non-maternal labor soon after normal delivery. It is said that in the Netherlands, expectant mothers drive themselves to the hospital to give birth, and after a normal delivery, if the doctor thinks it is okay, the mother even drives herself and goes home with her newborn baby. After graduating from medical school, I became a doctor, and although I am not an obstetrician or gynecologist, I believe that “moonlighting” is a bad practice. So I often wondered how such a bad practice became a tradition and was passed down from generation to generation, and even as the economic level improved, the bad practice of sitting on the moon became more and more prevalent, and the rules and regulations became more and more complicated. I think there are at least three reasons for the prevalence of this practice. The first reason is that the Chinese people lack scientific literacy and logical thinking habits and suffer from the disease of “taking things for granted”. In my article “Is the “take for granted” disease a cognitive defect? I have introduced some of the phenomena of the disease of taking things for granted and briefly mentioned the causes of the disease of taking things for granted. The phenomenon of the disease of taking things for granted is to deduce absolute laws or judgments based only on one’s limited experience or the teachings of one’s predecessors. In fact, the disease of taking things for granted reflects the immaturity of thinking patterns, the lack of discursive thinking ability, or the failure of thinking ability to reach the level of “metacognition”. The second reason is the common human tendency to overestimate the risk of survival and pursue excessive safety. Among them, because Chinese people lack scientific literacy and logical thinking habits, they are more likely to choose the irrational behavioral response of “believing in something rather than nothing”, and exaggerate the risk of infection and malnutrition in the postpartum period, thus forming a “set” This has led to the formation of a “set of rules and regulations” and even taboos for menstruation. The third reason is the compensatory effect of the low social and economic status of Chinese Han women. Historically, Chinese women’s long-standing low social status has created a latent sense of rebellion. However, because of the strong patriarchal power of the society as a whole, it was difficult for women to engage in reasonable and open resistance, so they had to resort to some disguised forms of expression. Thus, in the old China, where the importance of “heirloom” and the reproduction of the agricultural labor force was paramount, women emphasized their need for special care after childbirth through certain plausible taboos. Of course, the reasons for such treatment included the need to reproduce afterwards: if a woman became ill during the puerperium, she could lose her fertility. Especially in those days, the birth of a child was a “small death”, and the mortality rate of the old method of delivery was so high that it was a miracle to cross that threshold. As a result, maternity was given a different kind of “attention” and “care” than at other times, and it was passed down from generation to generation as a ritual that temporarily improved the status of women. Another tradition or taboo that supports my suspicion is the pardon for women to do “needlework” during the Spring Festival. There is a saying in my hometown that “lazy wives look forward to the first month”, meaning that women are not allowed to do “needlework” for a few days during the first month of Chinese New Year, so that women who usually have to do some sewing work can take a break. I am a layman as to what kind of care and recuperation a woman needs to recover her physical state after giving birth. But I am sure that obstetricians and gynecologists with a good medical background and a scientific way of thinking will have much more reasonable insights and suggestions. I think it’s time for all people to abandon the bad practice of “moonlighting”!
