The heyday of the Tang Dynasty had just passed. It was characterized by separatist vassal towns, monopolized power by eunuchs, fierce party struggles, frequent border troubles, financial difficulties, and poor people's livelihood. Although the empire still had a huge skeleton and cultural heritage, it was already showing signs of decline. Xu Ming was reborn as a descendant of a declining but still well-established family during the Tang Dynasty.
