A Chinese legend has managed to explain in a very convincing way:thumb represents parents. The index finger represents brothers,sisters and friends. Middle finger represents yourself. Ring finger (thefourth finger) represents spouse of his / her junior tuaj.Gishtirepresents your children.
Now join hands with palms palms, between your fingers together so as to be directed toward yourself, as shown in the picture and joinnormally and the other fingers.
Now try thumbs (parents) to remove from each other in parallel, youwill notice that they separated fingers, because your parents are not destined to live with you until your death, join fingers again.
Same way and with the index fingers (brothers, sisters and friends) and you will notice that and they will be separated, because each of them go in search of their fortunes, fingers together again.
Now try to separate small fingers (children) and you will notice that and they will be separated, becausewhen kids grow up and are able to go just works and then they leave, fingers together again.
