Dimples are located on both sides of the cheeks, and pear pits are located on the lower side of the corners of the mouth, about 1 cm. Pear pits are smaller than dimples and are not obvious. A tear pit is a dimple that appears on the cheekbone when a person smiles.

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. The formation of dimples is mainly genetic. It can also be obtained through plastic surgery.

Extended data:

1, dimple formation

Dimples are formed by muscle activity under the skin. Most muscles of human body are firmly attached to bones through tendon fibers, such as pectoral muscles and lower limb muscles. Whether there are dimples is related to the development of expression muscles. People with less plump smiling muscles and less subcutaneous fat on their faces generally have no dimples when they smile. Of course, dimples can also be made the day after surgery.

Dimples are recessive inheritance. Recessive inheritance means that the recessive genes in a pair of genes must be paired to show their determined traits. Dominant inheritance means that in a pair of genes, dominant genes do not need to be paired, and only one dominant gene will show its certain traits, such as sharp eyes and double eyelids. It can also be made by surgery the day after tomorrow.

2. The origin of pear vortex smile

Hu Lian An (1102—1180), a famous official, was born in Luling. Famous officials in southern song dynasty. Shaoxing years, peace, Jin Zhao Jiangnan. He invited Qin Gui and his henchmen, Wang Lun and Sun Jin, to be beheaded in public, and the name of loyalty and righteousness became a sensation all over the world. Qin Gui was furious, and Hu Quan was relegated to Lingnan for 10 years on charges of "arrogance, clamoring for people and abusing power for personal gain".

It was not until Xiaozong acceded to the throne that Hu Quan was put back into use. In Guangzhou, Hu Quan fell in love with a woman named Li Qian (Yuan Mei here said she was a prostitute). According to Li Qian, a married woman, recorded in Zhuzi Daquan Miscellaneous Meanings in the Song Dynasty, her husband discovered the affair between Hu Quan and Li Qian and forced Hu Quan to eat beans. "If not, kill it."

Later, Hu Quan and Li Qian returned to the north from the degraded land. On the way, I was drinking in Huyuan, Xiangtan. When I was slightly drunk, I wrote on the poem wall: "You are so grateful to be drunk, and there is a vortex in the pear cheeks." The so-called "pear cheek vortex" is Li Chiba.

So "pear vortex" originally refers to the dimple of Li Qian, a prostitute in the Song Dynasty. Later, it was generally called dimples on a woman's cheeks, a woman's smiling face, or a smile. Also known as "whirlpool".
