Nowadays, many people feel crazy when they see women's plastic surgery, but we must know that women's pursuit of beauty is endless, and it is not just modern women. Since ancient times, women have been willing to endure all hardships for beauty. There are some customs in history that we cannot understand. First, three-inch golden lotus foot binding is unique to China. I don't know when it started. Men like women's feet as small as possible, but not everyone has feet, so they have the bad habit of foot binding. Probably from the end of the Song Dynasty, it became popular in the Ming Dynasty and was really abolished in the Republic of China. Why is this a bad habit? Because foot binding is really cruel to women. Inevitably, the other four toes except the thumb will bend to the center of the foot, and the joints will be sprained and dislocated. The little feet wrapped in this way are distorted, but you can wear small embroidered shoes. And because the feet have no center of gravity, women who bind their feet walk on swings, which are like wicker swings to men and are very fragile. Once touted by the world. As a result, more and more women's foot binding has become a major symbol of women's pursuit of beauty. Secondly, girding the waist is a European custom. It is said that a female king in Europe was pregnant because of having an affair with someone. She didn't want anyone to see her big belly, so she wrapped it in a piece of cloth. Unexpectedly, she found that the waist can also stand out, with the popular square-necked low-cut dress at that time. Looking at the swaying and moving, it suddenly became the trend of the upper class. However, this is not enough for women. Later, corsets made of wood, whale bones and leather appeared, and even more frightening, they were made of iron. Of course, ordinary people can't afford a corset. Only senior ladies can make servants wear corsets. In order to make the waist thinner, women do not hesitate to damage their internal organs and deform their ribs. In order to have a thin waist, life is nothing. This is a bad habit that is more deadly than foot binding. It was not until the corset appeared that women were liberated. Third, black teeth are a popular custom in Japan. Generally, iron powder and gallnut are melted in strong tea or rice washing water, and then the teeth are dyed black. It is said that this is the symbol of distinguishing whether a woman has a spouse or not in Kamakura era. By the end of heian period, both women who started looking for spouses and aristocratic men began to pursue the trend of blackening their teeth. During the Warring States Period in Japan, the earliest age of getting black teeth was eight or nine years old. The purpose is simple, that is to say, this woman is mature enough to get married politically. In order to make a woman's black teeth look more beautiful, there will be a whole set of tooth dyeing tools in the dowry. In this way, the dark pool is no longer a symbol of maturity, but a representative of identity. After all, to keep your teeth black, you should not only soak the raw materials, but also apply them several times a day. For ordinary people who travel around, it is definitely impossible to make a living. Only people with money and leisure can keep their black teeth. It can be said that having black teeth also represents identity and status. Therefore, in order to improve their status, businessmen in the Edo era began to dye their black teeth. It is said that there is such a custom in some parts of Japan now, which looks really weird, but it is still very light to the body compared with foot binding and waist binding.
