Why wedding ring should put on the fourth finger?
Please follow the below step, really God make this a miracle (this is from a Chinese excerpt)
Firstly, show your palm, centre finger bend and put together back to back
Secondly, the rest 4 fingers tips to tips
Games begin, follow the below arrangement, 4 pairs, but only 1 pair can split at a time.

Try to open your thumb, the thumb represents parents, it can be opened because all humans go through sickness and die. Which means, our parents will leave us one day
Please close up your thumb pair, then open your second pair, this pair represents brothers and sisters, they do have their own family, and they will leave us too
Now close up your second pair, open up your little finger pair, this pair represents your children. Sooner or later they too will leave us, for they got they have their own life to live
Nevertheless, close up your little finger pair, try to open your fourth finger pair, on which we put our wedding ring; you will be surprised to find that it cannot be opened at all. Because it represents husband and wife, this whole life you will be attached to each other
Real love will stick together forever and ever
Thumb represents parents
Second finger represents brothers & sisters
Centre finger represents own self
Fourth finger represents your partner
Last finger represents your children
