Xu Liu

舊唐書

"舊唐書" by Xu Liu is a historical work compiled in 941-945 CE. The first classic history of China's Tang dynasty, it comprises 200 chapters covering imperial annals, treatises on subjects from astronomy to law, and extensive biographies. Though criticized for poor organization and later superseded by the New Book of Tang, this rapidly compiled work drew from earlier lost sources and ultimately regained acceptance as one of the Twenty-Four Histories.
