Why is a wife a husband's "wife's wealth" in numerology? Is the wife really the husband's private property?

The numerology of a wife's wealth does not mean that a wife is her husband's private property, but is analogized according to the principle of Yin-Yang and Five Elements. As we know, in the Book of Changes, men dominate Yang, women dominate Yin, and Yin and Yang must be compatible with each other. Judging from the different physiological characteristics of men and women, it also embodies the truth that men dominate yang and women dominate yin. A wife is wealth. Judging from the six rites of marriage in the Book of Rites, it takes money for a man to complete the six rites of marriage.
