It is not known when Li Zhirou was born. He was descended from Emperor Ruizong through Emperor Ruizong's son Li Ye (李業) the Prince of Xue (who was posthumously honored, by his older brother Emperor Xuanzong, Crown Prince Huixuan). Li Zhirou was descended through the line of Li Ye's descendants that inherited the title of Prince of Xue, including Li Zhirou's great-grandfather Li Quan (李琄), grandfather Li Sui (李邃), and father Li Mi (李宓).
