Due to the development of free love, the concept of girlfriend in people's minds has also developed from a single female friend to a female partner in a couple. People's understanding of "girlfriend" is "she is the woman who has a love relationship with you". Now everyone is open, and there is friendship between men and women. People call it a female friend, and the difference is different feelings.

Love:

Liànài is an expression of two people's love for each other. Different times have different definitions. The modern definition is that two people form the most sincere admiration for each other in their own hearts based on certain conditions and the ideal of loving each other, and are eager for each other to become their lifelong partners.

In primitive society, love has another experience, not simple monogamy. With the development of society, love is also developing in the direction of civilization, and its types are becoming more and more diverse.
