Li Longji, Emperor Xuanzong of the Tang Dynasty, had 66 children, including 37 sons and 29 daughters. Most of the harems of ancient emperors were filled with concubines, as was the case with Emperor Xuanzong of the Tang Dynasty.
As far as queens are concerned, Emperor Xuanzong of Tang Dynasty had three queens. The first queen of Emperor Xuanzong of the Tang Dynasty was Empress Wang, who was also his first wife. When Li Longji was still just the king of Linzi, the Wang family married him as his concubine. When Li Longji launched the "Tang Long Coup", the Wang family also gave him a lot of assistance behind the scenes. For this reason, after Li Longji ascended to the throne, Wang was also established as queen. However, Wang never had children after marrying Li Longji, so her status in the harem was shaken. Later, she was demoted to a commoner because of the "Fuyan Incident".
After Wang, Li Longji’s second queen was Concubine Wu Hui. As the grandniece of Wu Zetian, Concubine Wu Hui has always been favored by Li Longji. After being named Concubine Hui, her status and etiquette were the same as those of the queen. Concubine Wu Hui gave birth to seven children for Li Longji, four sons and three daughters. Concubine Wu Hui passed away in the 25th year of Kaiyuan. Li Longji, who had always doted on her, was deeply saddened by this. He also posthumously named Concubine Wu Hui the queen. Li Longji's other queen, Queen Yuanxian, was also posthumously granted the title because her son Li Heng succeeded him as Emperor Suzong of the Tang Dynasty.
Li Heng is the third son of Li Longji. The two older princes are Li Cong, born to Concubine Liu Hua, and Li Ying, born to Concubine Zhao Life. Among them, Li Cong, the eldest son of the emperor, was disqualified from being crown prince due to facial injuries. In addition to him, his mother had two other sons. The second son Li Ying was established as the crown prince in the third year of Kaiyuan, but was later demoted to a commoner because of the frame-up by Concubine Wu Hui and others. At that time, the two princes who were demoted with him were Li Yao and Li Ju. Among them, Li Yao, the fifth son of Li Longji, his mother Huangfu Deyi also had a daughter besides him, Princess Linjin.
The records of Li Longji’s children in historical records are not very comprehensive and accurate. Among his thirty-seven sons, there are thirty recorded in historical records, and another seven who died in infancy. People are only briefly mentioned because their biological mothers are not favored. In addition, the oldest of Li Longji's twenty-nine daughters is Princess Yongmu, who was quite loved by Li Longji after she was born. Regarding Li Longji's daughter, a Princess Pukang was mentioned in relevant records. However, it is speculated that this princess is probably not Li Longji's daughter, but Tang Yizong's. In addition, there are also discrepancies in the records of Princess Gaoyang in different historical books. Among them, the ancient book "Quan Tang Shu" clearly records the canonization of this princess, while "New Tang Shu" does not mention this princess at all. .
