However, some modern historians, based on the text on Li Xianhui's tombstone (written after Emperor Zhongzong was restored to the throne in 705), which suggested that she died the day after her brother and her husband and that she was pregnant at death, and the fact that the skeleton believed to be hers had a small pelvis, have proposed the theory that she was not ordered to commit suicide, but had, in grief over her brother's and husband's deaths, had either a miscarriage or a difficult birth and died from that. See, e.g., illustrations preceding the Bo Yang Edition of the Zizhi Tongjian, vol. 49. It may be notable that the Chinese Wikipedia article for Li Xianhui gave the text for her tombstone, but did not give an external link corroborating the text in the article.
