This sentence has a negative meaning, that is, boys cannot be born on the first day of the lunar month, and girls cannot be born on the 15th day of the lunar month. It is considered unlucky to be born on these two days, and some even change the birth date of the child. . I think this is unreasonable. If a boy is born on the first day of the lunar month and a girl is born on the 15th day of the lunar month, her life will be rough and bad. This has a strong superstitious color. In the backward ancient times, I don’t know how many people were harmed by such words.
The reason why this saying has been passed down is mostly related to China’s traditional festivals. Most of these festivals fall on the 15th day of the lunar month, the 15th day of the lunar new year, the Mid-Autumn Festival on the 15th day of August, the Lantern Festival on the 15th day of the first lunar month, etc. During these festivals, it is time for everyone to rest, and having children at this time will make everyone busy. The first day of the first lunar month is the New Year. Ancient medicine was backward. If you give birth to a child on this day, if you encounter dystocia or the child dies, the whole family will be shrouded in pain in the new year. The ancients believed that boys carry on the family line and add incense to the family. If a boy unfortunately dies in infancy, it will be even more sad. That's why there is such a saying.
The ancients believed that the "fifteenth" day was yin, and girls born on a yin day had a hard life and were difficult to discipline. The fifteenth day is the day when the moon is full, and it is also the day when the yin energy is the heaviest. The fifteenth day is also the day when ghosts are active. If a girl is born on this day and it coincides with the day with the strongest yin energy, she will definitely have bad luck. In some places, it is stipulated that married daughters cannot go back to live with their parents' families. If a girl is born on the 15th day of the year, her parents will miss her during the festival.
These are all without basis and are the product of ancient people's understanding of the laws of nature and some unexplainable phenomena. With the development of science, modern people have abandoned this backward concept. It's ridiculous to think that a child's fate can be determined by just such a sentence and the date of birth.
