The female author of the book,"The Beauty of a Concubine's Daughter," was called Huan Qingcheng, and the male author was called Yan Ruyu. This was an ancient romance novel. The plot had a sweet beginning and a cruel ending. I warmly recommend this novel to you. I hope you will like the story and characters in the book.
