In ancient times, in order to keep women chaste, something called palace sand was used as the test standard!

This kind of thing looks amazing, but it's just a bluff!

First of all, let me introduce this substance. The word "guarding the palace" has no special meaning and has nothing to do with the innocence of women. Shougong is the name of a female chameleon, which is a "domestic" chameleon in China.

This chameleon changes every year after the reproductive period, and the female body will be covered with a lot of estrogen. Male chameleons also secrete male hormones during this period, and chemical neutralization will occur after the combination of the two, resulting in the disappearance of the original hormones in female chameleons.

According to this phenomenon, the ancients began the "popular" activity of imprisoning the palace. When they are raised, they will feed them with cinnabar. When they reach a mature stage, they will smash the palace into sand with tools.

Apply this substance to unmarried women and leave a dot, which can form a mark. According to relevant records, if a woman has sexual intercourse, this scarlet spot will disappear, and the ancients used it to "identify" a woman's chastity.

However, from the perspective of modern science and technology, the animals guarding the palace do not have the above effects.

In the application field of traditional Chinese medicine, observing the palace can treat some children's diseases and symptoms of heartbreak and stroke, and it is a very comprehensive Chinese medicine material.

Someone used to make palace sand according to the ancient method. After finishing, they put it on their bodies, and as long as they get a little water, they will lose their traces. After staying in the body for three days, Shayin will be slightly "stubborn". So as long as you don't cheat, as the ancients said, you're not a fairy.

In the relevant records, we can also find some loopholes in the palace sand.

During Song Taizong's reign, there was a very powerful family named Lin Mi in Sichuan. Among his many wives and concubines, the fifth lady is particularly beautiful, versatile and very gentle. She was born in an official family in the previous dynasty, and her manners and temperament were outstanding. Almost every man will fall in love with her.

Because the concubine has so many benefits, Lin Mi will inevitably feel uneasy about going on a business trip, so she asked her friends to get palace sand and light it on the concubine's arm before going out.

After he went out, the woman didn't notice the cinnabar on her arm when taking a bath, so that the cinnabar was stained with a lot of water, and the whole scarlet mark disappeared. Coupled with the jealous attacks of other wives and concubines of Lin Mi, the concubine chose to commit suicide because of great humiliation.

Before committing suicide, she left a bloody book written with her own blood to prove her innocence, which is also a clearly recorded case of guarding the palace sand.

Therefore, from the above introduction and case analysis, it can be seen that Shougong Sha does not have the function of "identifying" women's chastity, but adopts a method of "psychological management" and puts scarlet dots on women's arms, so unsuspecting women are usually very careful, and normal people will not deliberately scrub with water.

Moreover, women will also restrain their behavior and dare not have sex with strange men at all. Therefore, psychological imprisonment is the biggest role of guarding the palace sand, but this imprisonment was obviously a means of oppressing women at that time. With the progress of the times, this kind of thing has disappeared.
