he had an older son, Li Kuan () the Prince of Li, as it was viewed by officials such as Cui Qun that Li Heng, born of a wife rather than a concubine, was the proper heir. Still, despite repeated petitions by the officials to create Consort Guo empress, Emperor Xianzong was apprehensive that, because of the prominent bloodlines that Consort Guo represented (being the granddaughter of the great general Guo Ziyi and the daughter of a princess), if she were created empress, other consorts would not dare to have sexual relations with him, and therefore repeatedly formed excuses with regard to not being able to find the right date to do so.

In summer 814, assassins that Li Shidao sent killed Wu Yuanheng and wounded Pei, terrifying the officials and the
