Test pregnant women give birth to boys and girls, but six have no children and grandchildren. what do you think?

I don't think so. First look at the divination bag. If there is no divination bag, divination is static, and we can see children and grandchildren, Yang is male and Yin is female. If there is any movement, we don't look at anything else, two look, and three look in the middle. Yang moves like a woman and Yin moves like a man.
