The word "dimple" comes from a small round pit specially made on the fermentation container in ancient times for the convenience of scooping wine. Some people have similar pits on their faces, so they are called dimples. There are dimples on the cheeks: cute and easy to be liked by elders. People with dimples make the opposite sex feel a little naughty and a little cute and warm.
When making a "smile" expression, facial muscles touch each other, resulting in a depression called "dimple". Some people call it "laughing nest", or because of its different location and size, it is also called "pear nest". Not everyone has dimples, but people who have dimples also have different shapes and heights. Under subdivision, dimples are located about 2-2.7 cm above the corners of the mouth, and there are three kinds of dimples: round, oval and fissure. Generally, dimples are the most obvious when you laugh. And there is a nest on the face, called pear nest. The pear nest is located below the corner of the mouth, about 1 cm. Pear nests are smaller than dimples, so they are not clear.
