What exactly does "Yan Ruyu" mean?

At first, "Yan Ruyu" didn't mean a woman named Yan or Yu. As the name implies, her appearance is like beautiful jade, which is used to describe the beauty of a woman or refer to a beautiful woman.

However, in Book Insanity in Strange Tales from a Lonely Studio, the author Pu Songling was interested by the phrase "Yan Ruyu in the Book".

Used in the form of a name on the heroine (a fairy in the book).

Nowadays, it is common to use "Yan Ruyu" as a female name in film and television works, and the word "Yan" does have its surname, so it naturally becomes a naming habit.
