Emperor Ai of Tang
Li Zuo was born in 892, at the main palace at the Tang imperial capital Chang'an. His father Emperor Zhaozong was already emperor at that point, and he was Emperor Zhaozong's ninth son. His mother was Consort He, who had previously given birth to an older brother of his, Li Yu, Prince of De, who was Emperor Zhaozong's oldest son.
Emperor Xuanzong of Tang
Emperor Xuanzong of Tang (; 8 September 685 – 3 May 762), also commonly known as Emperor Ming of Tang or Illustrious August, personal name Li Longji, also known as Wu Longji () from 690 to 705, was the seventh emperor of the Tang dynasty in China, reigning from 713 to 756 C.E. His reign of 43 years was the longest during the Tang dynasty. In the early half of his reign he was a diligent and astute ruler. Ably assisted by capable chancellors like Yao Chong, Song Jing and Zhang Yue, he was credited with bringing Tang China to a pinnacle of culture and power. Emperor Xuanzong, however, was blamed for over-trusting Li Linfu, Yang Guozhong and An Lushan during his late reign, with Tang's golden age ending in the Anshi Rebellion.
