I'm just a fan of online novels, so I can't provide the complete plot of 'Chu Qiao's Legend'. However, according to the information I know, Princess Yuan Chun's humiliation in the novel 'Chu Qiao's Biography' happened in the fifth chapter of the novel,'The Rebellion of Yanxun'. In this chapter, Princess Yuan Chun was betrayed by her own cronies and exiled to the frontier. Later on, Princess Yuan Chun's outstanding performance in the war eventually restored her reputation and status. However, she still suffered from the loss of her lover and child.
