The basic route of Xuanzang's trip: In 627 AD, Xuanzang set out from Chang 'an, sneaked into Yumen Pass, took Yiwu (now Hami, Xinjiang), went west along the southern foot of Tianshan Mountain, passed Aryan State (now Yanqi, Xinjiang) and Qu Zhi State (now Kuqa, Xinjiang), and crossed Lingshan Mountain. Came to Broken Leaf City (now southwest of tokmak, Kyrgyzstan). After the founding of the People's Republic of China (now east of Samarkand), it crossed the iron gate (now Buzgara Pass in southern Uzbekistan) and reached Tuholo (now northern Afghanistan). From here to the south, through the big snow mountain (now Hindu Kush Mountain), to Fanyangna country (now Bamiyan, Afghanistan), and to the east to Tolo country.

In the third year of Zhenguan in Tang Dynasty (AD 629), Master Xuanzang left Yumenguan for the west from Liangzhou, went through hardships and arrived in Tianzhu, and studied at Nalanduo Temple with Master Jiexian. Later, he traveled to Tianzhu to talk with local scholars and became famous. Seventeen years later, in January of the nineteenth year of Zhenguan, he arrived in Chang 'an. Emperor Taizong ordered Liang Guogong, Fang and other officials to hold a grand welcoming ceremony.

Master Xuanzang brought back hundreds of Buddhist scriptures, including 150 Buddha statues and Buddhist relics, and invited 520 folders of 657 original Buddhist scriptures and Sanskrit.

Emperor Taizong attached great importance to Master Xuanzang, respected his ambition of "interpreting the legacy", helped him to translate classics, established Chang 'an Translation Academy, and wrote to translate new classics.

Master Xuanzang organized the translation of Buddhist scriptures in Hongfu Temple, Jionji and Yuhua Palace, and translated 75 Buddhist scriptures and theories in 19, with a volume of 1335. The main classics are: 600 volumes of Mahayana Sutra, 0/00 volume of Land Theory of Yoga Master, 200 volumes of Sand Theory of Great Bodhisattva, etc.

The Buddhist scriptures translated by Master Xuanzang are often translated literally, and the brushwork is rigorous and accurate.

Master Xuanzang established new rules for translating classics, advocating loyalty to the original classics and word-for-word translation. Later generations often take the rules set by Xuanzang as the French translation. They call the classics translated by monks before Xuanzang the old translation, and the classics translated after Xuanzang the new translation.

The Buddhist scriptures and academic works translated by Master Xuanzang basically spread the Buddhist essence passed down from Nalanduo Temple in its heyday to China, which not only enriched the ancient culture of China, but also preserved precious books and records for the ancient Indian Buddhism and academic culture.

Master Xuanzang founded an important sect of Buddhism in China-"Only Knowing Sect" by translating classics and theories. This knowledge is extremely profound. In modern China, some scholars advocated carrying forward epistemology and establishing China's own science.

After returning to China, Master Xuanzang wrote a book "The Story of the Western Regions of Datang" at the request of Emperor Taizong, which recorded the history, geography, religion, myths and legends, customs and customs of 65,438 countries including the Western Regions, India and Ceylon. 1 10 countries were followers and 28 countries were hearsays. They are of great value and are important materials for studying the ancient history and geography of India, Nepal, Pakistan, Bangladesh and Central Asia. This book reconstructs the ancient history of India.
