She thought she was fighting over the legitimate concubines, but later she realized that what really trapped women was the secular ethics of this era. From rivalries to accomplices, the sisters join forces to break up the business bureau, protect the family, stabilize the Eastern Palace, and guard the borders. In the gap between the imperial power and the aristocratic families, they fight for the rights of property, livelihood, and life choices for women in the world.
