Why do ancient China literati like to write boudoir love poems? What is its literary value?

Boudoir love is one of all emotions, and most women in ancient boudoir have not experienced advanced culture and education, so it is difficult to put boudoir love into words, so there are special literati who write boudoir love poems for boudoir women to spread, which is an obvious value of boudoir love poems.

On the other hand, some boudoir love poems are actually not boudoir love poems, but talk about others through boudoir love. The author just compares himself to a woman in a boudoir and the monarch to a husband, that is, "husband and wife are used to describe the monarch and his subjects." The literary value of this kind of poems is mostly reflected in literary skills.
