The County Prince Is a Woman

She is the eldest son and heir of the Cheng family, but she is a woman, so she chooses to disguise herself as a man, making the Cheng family the head of the five major families. Her parents asked her to get married early to break the rumors, and finally chose Liu Muxi, the daughter of the Liu family.
