Different mouth movements usually mean different meanings. The ability of mouth to convey feelings is second only to that of eyes. In social activities, the upper and lower lips should be opened and closed naturally when speaking, and gestures with lips and pie mouth should be minimized. When standing, sitting or shaking hands with others, you can close your mouth slightly, don't show your teeth and keep smiling.

(1) pout, indicating slight unhappiness or dissatisfaction.

⑵ Lips with slightly exposed teeth. Show goodwill to each other.

(3) Make signal with the lips, indicating encouragement or support, encouragement and ridicule.

(4) smack your lips to express admiration or regret.

5] A pie mouth indicates contempt or disgust.

[6] Tight lips indicate serious thinking and treatment, or lack of interest in someone or something.
