When Kuang Heng was a child, his family was poor. In order to study, he chiseled through the wall of his neighbor's illiterate home and stole a candle to read, which finally touched his neighbor's illiteracy. With everyone's help, Kuang Heng Jr. learned something. During the Han and Yuan Dynasties, he served as a doctor, and was recommended by Shi Gao, a general of Fu and Che Qi, and moved to be a doctor.
