What are the abnormal manifestations of people when they lie
Action One: Hand: Touch the nose without self-sufficiency
The act of touching the nose is usually to rub the lower edge of the nose with your hand quickly, sometimes even slightly. The speaker touching his nose means that he is hiding his lies, and the listener making this gesture indicates that he is suspicious of the speaker's words.

Scientists have found that when people lie, a chemical called catecholamines is released, causing cells inside the nasal cavity to swell, causing the nerve endings in the nasal cavity to transmit a tingling sensation.
Action Two: Mouth: Will cover it with your hands without self-sufficiency
Consciously covering his mouth with his hands indicates that the liar is trying to restrain himself from telling those lies. Sometimes people cover their mouths with a few fingers or clenched fists, but the meaning is the same. Some people will pretend to cough to cover their mouths.
Action Three: Eyes: Will look at the Lord away without self-sufficiency
When trying to cover up a big lie, it's likely to turn your face away to avoid the listener's attention.
Action Four: Limbs: Scratch your neck without being self-sufficient
The action of scratching the neck is to scratch the area on the side of the neck that is located under the earlobe with the index finger (usually the index finger of the hand used to write). When the spoken language does not coincide with this gesture, the contradiction will be particularly obvious. For example, if someone says, "I understand your feelings very well," but at the same time he is scratching his neck, he doesn't actually understand.
Action Five: Action: Pulls on the collar without self-sufficiency
Lying causes sensitive facial and neck nerve tissue to itch, so people have to eliminate the discomfort by rubbing or scratching. This phenomenon explains not only why people scratch their necks when they are confused, but also why liars frequently pull on their collars when they are afraid that a lie will be recognized.
Sometimes a lot of body language can give us a lot of hints, and we can know whether the other person is lying through some body movements.
