Here, I'll tell you a proverb from the countryside: "A man who accounts for 38 is a scholar, and a woman who accounts for 38 is a widow." At first glance, this sentence likes to be passed around in the circle of rural elderly. There is no factual basis or scientific reason, but as entertainment, just talk casually and see what it means.
In rural areas, I believe some superstitious people think that boys born in grades 8, 18 and 28 will be more blessed. The so-called scholar is related to the eighth grade. Boys born these days will be more promising, become officials and have money.
In other words, there is a special expectation for boys born on the eight related days. It is better not to say that superstition is a blessing. For girls, this sentence is a bit too much. I think girls born now are easy to be widowed after marriage. Of course, this is just a superstition. In traditional culture, the prejudice against women is obvious, and no one talks about it in modern society. Everyone's achievements are achieved by both hands, and not everyone can sit down.
