An aunt of hers (Liu Dewei's second daughter; 627 - 12 June 675[6]) was married to Prince of Guo Li Feng, the 15th son of Emperor Gaozu of Tang.
They had three children—a son named Li Chengqi, and two daughters (the later Princesses Shouchang and Dai).
In spring 684, Emperor Zhongzong showed signs of independence from his (and Li Dan's) mother Empress Dowager Wu (later known as Wu Zetian), who wielded most of the imperial power, and she deposed Emperor Zhongzong, replacing him with Li Dan (as Emperor Ruizong), but held power even more securely after that point.
To attack him, she decided to first falsely accuse Crown Princess Liu and one of Wu Dan's concubines, Consort Dou, of witchcraft.
He therefore carried out ceremonies where their spirits were summoned to caskets to be buried at an imperial tomb.
