Red is the color of rouge, and face is face. Ancient women moistened their faces with rouge, which looked like red faces from a distance, so they were called beauties.

Its earliest source can not be found now. Looking through the ancient books, we can only see that the earliest book, Hanshu Volume 97, Biography of Consoles 67, is "exciting and anxious, full of beauty and prosperity." The beauty generation here refers to Li Furen, the favorite concubine of Emperor Wu of Han Dynasty.

There is also a kind of "beauty is unlucky". It is popular to say that a woman's life is thin, and the old saying goes that a beautiful woman dies young or her husband is unhappy.
