Nayin fortune-telling believes that people’s marriage is not destined by fate, because fate is dead, but luck is living. Often external factors will affect a person’s destiny the day after tomorrow. If you meet a noble person to help, it can turn evil into evil. Ji, and if you encounter villains causing mischief, good things often turn into bad things. If you go to a place with many boys and girls, marriage will be suppressed. In different social systems, the concept of marriage is different. Matriarchal society is group marriage and Odd marriage is the mainstay, but it is different in patriarchal society. There are differences between feudal slave society and democratic society. However, human beings grow up in nature that changes periodically. Natural periodic changes have relatively unchanging rules, and the same is true for human marriage. , such as spring is warm and flowers bloom, summer is long, autumn is harvested, and winter is hidden. When people are young and in their prime, this is a period when marriages are frequent, but this is not the case in old age. If Nayin fortune-telling can master these rules, it can predict the changes in marriage.
