The prototype of Tang Sanzang, one of the protagonists in The Journey to the West, is Xuanzang, a famous cultural messenger in ancient China. In the third year of Zhenguan (AD 629, the first year of Zhenguan), Emperor Taizong left Liangzhou and headed west to Yumenguan, and went through all the difficulties to reach Tianzhu. I first learned it from Jiexian in Nalanduo Temple. Later, he traveled to Tianzhu to talk with local scholars and became famous. Seventeen years later, in the nineteenth year of Zhenguan (AD 645), he returned to Chang 'an.

When Xuanzang's disciples wrote The biography of Master Sanzang, they commented in the preface: "In the seventeen years of Spring and Autumn, Xuanzang heard about 130 countries, praised the majesty of my emperor, restrained the arrogance of different learning, and painted it as a teacher's great ambition. The famous gentleman bowed his head and the winner rubbed his shoulders, but only one person. "
