Liu Zhi had no choice but to marry into the palace because her sister died in childbirth and became the stepmother of the infant prince Xiao Yun. The palace is cold and has complicated rules. From the initial ignorance, she took charge of the harem step by step, growing up quietly amidst the warmth and warmth of human relationships and the undercurrent of the court. She sticks to her heart and protects the prince to grow up safely. She has always been calm and self-possessed despite the turmoil in the harem and changes in the palace. In the end, she helped Xiao Yun successfully ascend the throne and take charge of the country. She shed her honor as Queen Mother, broke away from the shackles of the high palace walls, regained her original intention of helping the world by hanging the pot when she was young, and rushed to the free world to start a new life of her own.
