Is the yellow calendar accurate for boys and girls?

Generally speaking, it is not allowed, but sometimes it is not scientific to allow this method. Anyway, the child is either a man who makes calendars or a woman who makes calendars, and is not responsible for compiling and publishing. However, I have seen several versions of this calendar, and some versions are much worse. . . There are always different stories. . . Believe it or not, I don't believe it myself, but your friend is still very young. Hehe, it makes no difference to have boys and girls now. I just pay too much attention to this and my health and happiness.
