Different smiles come from different ways.

The common feature of laughter lies in its joyful color and relaxed expression.

The personality of laughter lies in the fact that the specific eyebrow, lip, tooth and voice are often different in operation and coordination.

Taking the smile as an example, it can be roughly divided into four points: first, the forehead muscles are contracted to raise the eyebrow position, and the eyebrows bend slightly into a lunate shape.

Secondly, the laughing muscles on both cheeks contracted and stretched slightly, which made the facial skin look like a smile.

Once again, the lip muscles are fitted together, the lips are slightly curved, the corners of the lips are slightly raised, the lips are closed, and the teeth are not exposed.

Finally, consciously control the sound system, generally do not laugh.

Generally speaking, when we laugh, we should pay attention to three aspects: 1. When we laugh and laugh, we should be consistent with each other and make the smile complement each other's manners and conversation.

Don't laugh at your face, speak rudely, behave rudely, or be elegant in language, behave in a proper way, but have no smile.

Both of these two situations are doubtful of their attitudes.

(2) a person who has a good temperament and laugh will not only pay attention to the timing and enjoyment of laughter, but also pay attention to the spirit and elegance of laughter.

Genuine laughter should be from the heart, so it reflects people's cultural accomplishment and spiritual pursuit very naturally.

If we laugh carelessly and behave vulgarely and presumptuous, we will destroy our personal image.

(3) harmony and laughter. From an intuitive point of view, it is actually a coordinated action of eyebrow, eyes, nose, mouth, teeth and facial muscles and sounds.

Therefore, when laughing, we need to make every part of the movement in place, not to be warm, but to cooperate successfully.
