李吉甫
In 784, during the reign of Emperor Daizong's son Emperor Dezong, when Li Jifu was 26, Li Jifu became a "Taichang Boshi" (), a consultant at the ministry of worship (太常寺, "Taichang Si"), and became known for his knowledge, especially the past Tang tradition, and was often praised for it. In 786, when Emperor Dezong's wife Empress Wang died, the regulation on the proper rituals were missing – as there had not been an empress who was mourned since the times of Emperor Suzong's father Emperor Xuanzong. Li Jifu planned the mourning ceremonies for Empress Wang, and was much praised by Emperor Dezong.
