Once Jin Yong(The famous Wu xia novel author) comments about the
love life of mordern life and the time of his novel stories.
He explained that the reason why ppl in the ancient time are more
loyal and more chance of "love in first sight" is becuase the
communication technology is not as good as the mordern time.
In the ancient time, when they meet someone by chance, and has good
feeling about him/her, they will choose to be this someone
forever.(become lovers, or "jie bai" as brothers/sisters) Becuase
once this someone is gone, it's quite impossible to contact him/her
again. So they treasure the chance of first meeting. For us who
living in the mordern age. It's very easy to contact everyone. You
lose a fren, you find a new one easily. You break with your bf/gf,
just call her and try to patch back if you want. Or you just go out
and find someone else. In the ancient time, the chance the you meet
new ppl are more slim than the in mordern time, so they treasure
relationship with the ppl they already know.
