Expression

Facial expression is the reaction action of the parts of the head (mainly the face) to the emotional experience.

Any other facial expression occurs between laughing and expressionless poles.

Other facial expressions occurring between the poles are manifested in two forms of emotional activity: pleasure (pleasures, happiness, pleasure, excitement, excitement) and unhappiness (such as anger, fear, courage, pain, disdain, scorn, surprise).

When you are happy, your facial muscles are horizontal, your eyebrows are light, your pupils are magnified, your mouth is upturned, your face is short. The so-called "eyebrows and beards are laughing into a pile". When you are unhappy, the facial muscles are lengthwise and elongated, and the faces are longer. The so-called "pull like a horse face".
