Why don't you laugh? In fact, among ancient beauties, her face is beautiful, her nose and eyes are in harmony, but her teeth are bad and she dare not laugh. In fact, when you smile, let's look in the mirror. If you don't show your teeth, you will appear to be particularly treacherous. The grin was bright and sunny, but there was nothing I could do. His teeth are not good-looking, so you smile like that. It is a very bad way to smile without showing his teeth, so no matter how good his teeth are, he will show his teeth when he smiles, making him look sunny, open and confident. Not showing your teeth is completely different from being angry.

The ancients said: Smile without showing your teeth. In fact, you just need to be subtle and gentle, so you don't have to laugh. If necessary, you can block your smile with your hand, which is not rude but elegant.
