You learn something new every day.

Why should the wedding ring be worn on the fourth finger? There is a beautiful and convincing explanation given by the Chinese.

The thumb represents your parents.
The second finger represents your siblings.
The middle finger represents yourself.
The fourth finger represents your life partner.
The fifth finger represents your children.

Firstly, open your palms, face to face, and bend your middle fingers and hold them together, back to back. Secondly, open and hold your remaining three fingers and your thumb tip to tip.

Now, try to separate your thumbs, which represent your parents. They will open, because your parents are not destined to live with you for the rest of your lives. They will leave you sooner or later. Now, join your thumbs as before and separate your index fingers, which represent your siblings. They will also open, because your brothers and sisters will have their own families and will have to lead their own separate lives. Now, join the index fingers and separate your little fingers, which represent your children. They will open too, because your children will grow up, get married and settle down on their own some day. Finally, join your little fingers and try to separate your ring fingers, which represent your spouse.

You will be surprised to see that you just cannot separate them, because husband and wife are meant to be together all of their lives, through thick and thin.
