In the original novel, the Crown Prince was deposed and imprisoned in the Eastern Palace. In the TV series, the Crown Prince was not deposed. In the 46th episode, in order to bring down the Crown Prince, Princess Royal Li Yunrui handed Si Lili and Xiao En's confessions to the Second Prince. When the Crown Prince found out, he went to the Royal Palace to apologize to the Qing Emperor.

In the 47th episode, the Eldest Princess Li Yunrui and the Crown Prince plotted a rebellion and attempted to assassinate the Qing Emperor. However, their plan was seen through by Fan Xian and the others and ultimately failed. The prince was deposed, demoted to the common people, and imprisoned in the East Palace.
