In the 20th episode of the Eastern Palace TV series, the Second Prince was sentenced to death because he framed the people of Dan Chi, murdered the original Crown Prince, and launched a coup. This TV series was based on the novel of the same name and was starred by Chen Xingxu and Peng Xiaoran. The other princes also had their own reasons for not being able to become the Crown Prince. For example, the Third Prince was exiled, and the Fourth Prince took the initiative to request to go to Jiangnan. Therefore, before Lil Feng married the Second Prince, Li Chengyin became the Crown Prince.
