The Concubine of the General's Mansion

I am the concubine of the general's residence, and my father is the general who protects the country. When he was seven years old, my father, mother, and elder brother were ordered to go outside the Great Wall to suppress the rebellion. I am left alone in the general's mansion. But in the same year, my parents picked up an orphan girl during the war and took her with them as their adopted daughter. The emperor thought that I was young and lonely, so he made me the Princess of Feng'an, and even asked the queen to take me into the palace and raise me personally. He allowed the princess to bully me, ignored the prince's teasing me, and even punished me deliberately. Finally, I waited until my parents returned home triumphantly, thinking that I was out of trouble, but found that I was dispensable to them.
