When it comes to the fingers on your hands one Chinese legend has special significance.
Due to that legend: thumbs characterize parents and index fingers are representing brothers, sisters and friends. The middle finger symbolizes you, while the ring finger symbolizes your partner, and the little finger are your children.
Fold your hands palm to palm, then put middle fingers in the like it is shown in the video. Separate your thumbs (parents), and you will see that they are separated just because they are the ones who will live with you forever. Then, fold them again.
Separate the index fingers (brothers and sisters), and youll see that it is possible because they are the ones who regularly go as they have their own life tracks.
Separate the small fingers (children). It is also possible because children grow and go through life. Then, fold them again.
In the end, try to separate your ring fingers (partners). Are you surprised? It is impossible to do.
