Xuanzang not only translated Sanskrit Buddhist scriptures into Chinese, but also was the first translator in China to introduce China's works to foreign countries and let them know about our ancient culture. He was the first person to translate Laozi's works into Sanskrit. Indian scholars commented on Xuanzang: "There is no such great translator outside China. In the cultural history of all mankind, we can only say that Xuanzang was the first great translator. " Jian Zhen established a strict discipline system in Japan for the first time, which put Japanese Buddhism on the right track, facilitated the government's control of Buddhism, put an end to all kinds of disadvantages caused by neglect of management, and made Buddhism the national religion of Japan.
