In " Celebrating Years," the personal relationship between Eldest Princess Li Yunrui and Crown Prince Li Chengqian was discovered by the Qing Emperor. The Eldest Princess Li Yunrui and the Crown Prince Li Chengqian had an affair under the Qing Emperor's nose. They were discovered by the Director of the Overwatch Council, Chen Pingping, and the head of the palace treasury, Fan Jian. In order to bring down the Eldest Princess and the Crown Prince, the two of them handed the letter of Li Yunrui and the Crown Prince's adultery to the Emperor. When the Qing Emperor learned of this, he was furious and placed Li Yunrui under house arrest in the manor. At the same time, he deposed the Crown Prince's position as Crown Prince.
