Xuanzang (602-664), common surname Chen, first name Yi. A native of Luozhou (now Yushi Town, Henan Province). Founder of Tang Buddhism's Only Knowledge School, and translator of Buddhist scriptures. Xuanzang "is involved in scripture theory, and he has tasted that the translators are often wrong, so he seeks differences in the Western Regions to participate in it."

627(the first year of Zhenguan of the Tang Dynasty) In August, he left Yumen Pass in the west and traveled long distances. He crossed Lingshan (now Musuo Ridge), which is covered with snow all year round, went to his parent leaves (i.e. Broken leaves), crossed the Wuyou River (Amu Darya), climbed Tiemen Pass (Badak Mountains in present-day Afghanistan), passed through Tocharah, and entered northwest India.

In 631 AD, a dusty-faced monk came to India. He traveled to various states of India and preached the teachings of Mahayana Buddhism. He became famous and attracted the attention of King Jieri, who was Chen Xuanzang from China. King Jieri specially held an uncovered conference for Xuanzang in the capital Qu Nvcheng in 642. More than 20 princes and more than 5,000 senior scholars of Mahayana Buddhism and Brahmanism attended the conference. Xuanzang preached the teachings of Mahayana Buddhism. No one could refute him, so he was given the title "Mahayana Heaven". After the conference, King Jieri asked Xuanzang to ride an elephant around the world and preach the saying. For a while, he set off a "China fever" in India. In fact, it also used this to unify Buddhist teachings and eliminate disputes. Xuanzang was also invited to the Sixth Buddhist Congress in 643. Xuanzang translated Chinese classics such as the Tao Te Ching into Sanskrit and brought back a large number of Buddhist classics from India.

In 643, Xuanzang set off for his return to China, and after returning to China, he also wrote "Records of the Western Regions of the Tang Dynasty" to introduce Indian culture.

On February 25, 645 (the 24th day of the first month of the 19th year of Zhenguan of the Tang Dynasty), he returned to Chang 'an with 657 Sanskrit Buddhist scriptures and various Buddha statues. Later, he specialized in translating Buddhist scriptures. In 20 years, a total of 75 scriptures and 1335 volumes were translated, which had a great impact on Buddhist thought in China.

He died on the fifth day of the second lunar month in 664.
