The language of the mouth

The mouth is also the most expressive part of the face. Open and close, forward and backward, up and down, close and relax - the mouth can form complex movements and convey rich meaning through four basic ways.

People with closed lips can keep secrets. Such people are very cautious about their own words and deeds, cautious to often appear overly sensitive.

The curve of the lips can naturally expose the inner activities, as the writer A. Tolstoy said: "the mouth is not good at pretending." In different situations, people's mouth will have different expressions: the corners of the mouth will be turned down when they despise, they will be tongue tied when they are stunned, they will bite their lower lip when they are patient, they will turn up when they smile, they will tremble when they are angry, they will pout when they are wronged, and they will gnash their teeth when they hate. You can really reflect your inner activities with your mouth.

Besides reflecting people's inner activities alone, the mouth can also express emotions clearly when cooperating with other facial organs. If a person's mouth grins backward, facial muscles move up, eyes become thinner, etc., this is a happy expression. On the contrary, drooping corners of the mouth, downward movement of facial muscles and tight frowning are common features of unpleasant expressions such as pain, despair, sadness, anger and fear.
