Human beings believed it a long time ago. When a person is born, he is only half, incomplete. You must find your other half and become a couple to be complete and happy.
Human beings also believe that above the nine heavens, there is an old god named Yuelao. He specializes in earthly marriages. He has a kind of red thread, named: red thread. After each baby is born, a red thread is wrapped around their ring finger. The other end of the thread is the other half of their life. Even if they are thousands of miles apart, they can still find each other, fall in love and get married.
Over thousands of years, the red thread has created thousands of couples, and people respect it even more, but something went wrong this time.
There are three red lines on a person's ring finger!
