In the fifteenth year of Zhenyuan, Chang'an.
Yuan Zhen, a fifteen-year-old boy from a poor family, knocked on the door of the Bai family with his hands red from the cold, just to borrow a copy of the Book of Songs.
Bai Juyi, the 28-year-old son of an aristocratic family, opened the door and saw the young man whose eyes were brighter than the lights in Chang'an. He handed over the book with a smile, then took off his cloak and put it on his shoulders.
This encounter lasted thirty years.
Purpose: Only for one person in life
