唐高宗
Xu Hun (, fl. first half of ninth century) was a Chinese poet. He was poet in the Tang poetry tradition of the Tang Dynasty. By passing the rigorous requirements of the imperial examination system, he received his "Jinshi" degree, in 832, and subsequently followed a "moderately distinguished" professional scholarly career. Xu Hun was descended from Xu Yushi, who was Chancellor under Emperor Gaozong of Tang.
