On 29 January 655, Wu Shun's sister, Consort Wu gave birth to Li Xian. Li Xian was Emperor Gaozong's sixth son. After an intense power struggle involving Consort Wu, Empress Wang and Consort Xiao, Consort Wu became Empress. Li Xian was created the Prince of Lu. However, there were rumors inside the palace that the Crown Prince was not actually born of Consort Wu but of Wu Shun, Lady of Han.
