I recommend " The Smiling Concubine " to you because the female protagonist's surname is Mo, which matches the surname in the title. Moreover, the female protagonist is a half-ghost, which also meets the requirements. This book was an ancient romance novel. The main character, Mo Xiaoxiao, traveled to the age of thirteen. She had many sharp edges and was a female devil from her previous life. The story was quite rich and worth reading. I hope you like my recommendation.
