The Lie-Nyu Zhuan, written by Liu Xiang in the Han dynasty, is the first female biography in Chinese history. There are 7 chapters in this book: ”Manner of Female”, ”Virtuousness and Ability”, ”Benevolence and Wisdom”, ”Obedience with Morality”, ”Ethical Behavior with Righteousness”, ”Eloquent Communication”, and ”Sin deed”.

The definition about ”Lie” from Liu Xiang means ”Listing”-listing all types of females. The purpose of his writing is not to honor females in virgin chastity.

And we also expect to figure out how the shift of chastity definition is
