He is the prince's teacher and is only four years older than the prince.
"Why is the teacher so distant?"
"You know everything..."
They will eventually leave, and they will eventually meet.
He was originally the prince of a country, but was tricked by the emperor's younger brother and the throne was changed. He was banished to a desolate place for four years. He was demoted here for four years and fled everywhere. He came to Daqi and met the young man.
"Your Majesty, a common man can be a Tutor, but after four years, the common man must leave."
The old emperor wondered "Why?"
Jing Xiao remained silent and just followed the old emperor to see the prince.
"Your Highness, my name is Jing Xiao, Jing from Chunhe Jingming, Xiao from Xiao Suo."
"Teacher, my name is Bai Yan, courtesy name Ziyu."
Four years later, Jing Xiao left without saying goodbye, and Bai Yan lost his memory, so "Jing Xiao" became a forbidden word in the entire palace.
See you again three years later, Jing Xiao becomes a prisoner...
