Guo Ziyi
In 764, Li Kuo was made crown prince. Emperor Daizong then tried to transfer his title of "Shangshu Ling" to Guo Ziyi, but Guo declined on the basis that only Li Kuo had held the title recently, and previously the title had been held by Emperor Taizong. Meanwhile, in 765, a Buddhist nun named Guangcheng () claimed to be Li Kuo's mother Consort Shen, but after further interrogation, it was discovered that she had only been Li Kuo's wet nurse, and Emperor Daizong had her whipped to death.
