     The size and shape of your ears show your character more than any other parts of the face. Other

parts of the face change shape as we get older, but ears do not change their shape. They only change in

size.

     Reading people's character from their ears is an old science. In very old times people thought that a

person with big ears had a good and generous character. They thought that a person with pale (nearly

white), small ears was dangerous. They also thought that the shape of the ear showed whether a person

was musical or not. Today, too, many people believe that the size and the shape of the ear help you know

if a person is musical.

     Ears are all different, and each characteristic has a meaning. Next time when you look at a person, see

if his ears are large or small. Look at the lobes (the lowest part of the ear). Are they attached (连着) to

the face? Ears that are always red mean a person may easily get angry, or he / she just has high blood

pressure (高血压). Ears that are always cold and pale mean a person has a nervous character. And a big

inside hole of the ear means a person is musical.
