Jian Zhen, originally named Chunyu, became a monk at the age of 14. Thanks to his efforts, he became a learned monk after middle age. In 742 AD (the first year of Tang Tianbao), at the invitation of Japanese monks, he made six trips to the east and finally arrived in Japan in 754.

He stayed in Japan for 10 years and tirelessly spread the cultural achievements of the Tang Dynasty. He brought many books and cultural relics. The people who go with them know art and medicine.
