Cui Shu'er, the concubine of the Crown Prince, was whipped by the Crown Princess on her wedding day. She held back and showed weakness by being meek, but in fact she was doing everything for her. She took advantage of the crown prince's recklessness and jealousy to pave the way for her promotion, from concubine to queen, and then to the queen mother who listens behind the curtain. She doesn't want favor, she just wants power, and ultimately holds her destiny firmly in her own hands.
