Five Tang emperors after Taizong also honored officials whom they felt have contributed greatly to the empire, by hanging their portraits in Lingyan Pavilion. Such officials include Guo Ziyi (honored by Tang Daizong and Tang Dezong) and Li Guangbi (honored by Tang Suzong), who were vital in putting down the An Lushan Rebellion. In a twist of fate, Chu Suiliang, whose calligraphy was used when honoring the original 24, was posthumously inaugurated into Lingyan Pavilion by Tang Dezong, and again by Tang Xuanzong, Li Chen.
