당 고종
On his return to China in AD 645, Xuanzang was greeted with much honor but he refused all high civil appointments offered by the still-reigning emperor, Emperor Taizong of Tang. Instead, he retired to a monastery and devoted his energy to translating Buddhist texts until his death in AD 664. According to his biography, he returned with "over six hundred Mahayana and Hinayana texts, seven statues of the Buddha and more than a hundred sarira relics." In celebration of Xuanzang's extraordinary achievement in translating the Buddhist texts, Emperor Gaozong of Tang ordered renowned Tang calligrapher Chu Suiliang (褚遂良) and inscriber Wan Wenshao (萬文韶) to install two stele stones, collectively known as "The Emperor’s Preface to the Sacred Teachings (雁塔聖教序)," at the Giant Wild Goose Pagoda.
