Generally speaking, the reason why people enter into marriage is to meet certain needs. Society has a great influence on any individual's mate selection criteria. Personal mate selection is not only restricted by social structure, but also influenced people's mate selection behavior through huge cultural traditions, customs and habits, which creates strong pressure on unconventional mate selection.
Therefore, society has great restrictions on personal mate selection. Specifically, unmarried men and women should consider at least two criteria when choosing a spouse, namely, social attribute criteria and natural attribute criteria.
