唐昭宗
Jing Yanguang was born in 892, during the reign of Emperor Zhaozong of Tang. His family was from Shan Prefecture (陝州, in modern Sanmenxia, Henan), but all that is said about his family in traditional sources is that his father Jing Jian () was a capable archer and trained Jing Yanguang to be one as well.
