A nickname of the Korean savior handed down since the Joseon Dynasty.
It is said that if JeongDoRyeong appears, the nation will become wealthy, and if JeongDoRyeong appears, life will be prosperous and the harvest will be abundant.
Notably, the GyeokAmYuRok secretly describes JeongDoRyeong’s appearance. Rather than referring to a male child with the Jeong surname, he is referred to as JeongDoRyeong, referring to a person who spreads the right path.
