Men and women who are in love all seek beauty, wealth, and soul, but they are bound by their own conditions, and under the competition between men and women, they tend to be equal - good to good, inferior to inferior, superior to inferior, superior and inferior. Wait for it, and if you don't wait for it, you will scatter, and the advantages and disadvantages will be obtained, and the natural choice will also be.

There are three conditions for equivalence:

Equal response - male and female appearance, wealth, and soul are matched accordingly, and they are perfectly matched, which is called "golden and jade relationship" or "door to door", which is one of them;

Dislocation and reciprocity - the appearance, wealth, and soul of men and women are very different, and there is no correspondence, so there is a mismatch between appearance and wealth, appearance and soul, and the advantages and disadvantages complement each other, and each takes what it needs. Women take appearance as assets, and men take wealth and soul as notes, which is called "Lang Cai Girl's Appearance" or "Lang Cai Woman's Appearance", which is secondary;

Gradient equality - male and female appearance, wealth, soul strategy, etc., are different, or high or low gradient, looking for and seeking, corresponding to it, and dislocation can not be, but it is limited by the time situation, and there is no other, it is a combination of grinding and seeking common ground while reserving differences.

There are few first-class people, there are many second-class people, and the third-class people should be many.

Men and women in erotic love do not want to pursue beauty in appearance, money, and noble soul (the opposite sex), but they are limited by their own objective conditions, coupled with the fierce competition between unmarried men and women, they can only tend to have equal conditions on both sides -- those with superior conditions find those with superior conditions, those with poor conditions find those with poor conditions, and those with excellent conditions (the conditions of both parties) are equal. Marriage and love with equal conditions will be achieved, and marriage and love will be broken up if the conditions are not equal, and those with superior conditions and those with poor conditions will have their own place, which is a natural choice.

There are three situations of reciprocity of conditions:

The first is the equivalence of the (conditions of both sides) - the appearance, money, soul and spirit (conditions) of both men and women are matched and matched, and people call it "gold and jade relationship" or "matching", which is the first kind of equivalence;

The second is the mismatch (of the conditions of both sides) -- the appearance, money, soul and spirit (conditions) of men and women are very different and cannot be corresponded to one by one, so there is a mismatch between the woman's appearance and the man's wealth or the woman's appearance and the man's talent, and the advantages and disadvantages of the (both sides) make up for each other, and each takes what he needs. Women use beauty as capital, and men bet on money, wealth or talent, and people say that they are a match of "rich women" or "talented women", which is the second kind of equivalence;

The third is (the conditions of both parties) gradient equality - both men and women are unsatisfactory in appearance, money, soul and spirit (conditions), some (conditions) are higher than each other, some (conditions) are lower than each other, in a ladder oblique state, repeatedly searching, (how) can not correspond one-to-one, dislocation and reciprocity can not be completed, but because of the age of marriage and the restrictions of the environment, (in their own narrow environment) there is no better condition to look around, so they can only reluctantly get together to run in, seeking common ground while reserving differences, This kind of reciprocity is more common for men (conditions) than women, and less for women (conditions) than men, which is the third type of reciprocity.

The first type of equal men and women is very rare, the second type of equal men and women is more common, and the third type of equal men and women is too common.
