Why did the mother slip a book before the ancient woman got married?

In ancient times, women's marriages were basically "parents' orders and matchmakers' words", so many women didn't know what kind of person they were going to marry before they got married. Not to mention knowing something about the wedding night, so many women know nothing about the small graduation before the wedding night.

However, in order to prevent their daughters from making jokes on their wedding night, many parents will secretly slip a book to women before they get married, so that they can know about the wedding night in advance, so as to avoid the newlyweds being unhappy. Later, someone also compiled a book specifically for these contents, called Su Nv Jing.

By the end of Ming Dynasty, in addition to Sutra of Plain Woman, many related works were derived, among which Tang Bohu, one of the four great painters in Ming Dynasty, was the most famous. Since Tang Bohu was framed for cheating in the imperial examination and Wang Ningzhi's rebellion, he looked down on officialdom and made a living by painting himself. Among them, those paintings depicting men and women were the most impressive, which were very popular in the middle and late Ming Dynasty.

In the Qing Dynasty, Emperor Kangxi gave an order to destroy all the paintings of men and women in the Ming Dynasty, leaving little. However, unlike in ancient times, before a woman got married, her parents didn't need to secretly copy a copy of the Soviet policewoman. Instead, they may need to worry about other things.
