The etymology of big miss

Big Miss refers to the unmarried daughters of big families of high officials and dignitaries in the old society, especially the daughters of powerful families such as emperors and princes, and is honored as "Big Miss". Sometimes they are also called "ladies" or "ladies". As a title, "Miss" originated from which dynasty, which generation, which ancient book and which law it came from. I am afraid that no one has verified it, and it is also difficult to verify it. The original meaning of this word has changed greatly in the long river of history. In ancient times, all the people called Miss were young unmarried women from official and wealthy families, such as wealthy ladies and unmarried housewives from educated families, who were entitled to the title of Miss. A girl from a poor family, no matter how young and beautiful, is also a "servant girl's life." However, the popular "miss" has another ironic and gray meaning, which is completely different from the original intention in ancient times. It is no longer a delicate nickname, a symbol of status, a show-off of a rich official, a concern, love, envy and jealousy, and has almost become a special vocabulary for "prostitutes" in Huajie Liuxiang.
