Guo Jing
Yang Guo's birth is briefly mentioned at the end of the first novel. Mu Nianci met Guo Jing and Huang Rong shortly after giving birth to her son. Guo Jing, who was Yang Kang's sworn brother, hoped that Yang Kang's child will not follow in his father's footsteps. He named the baby boy "Guo", which means "wrong" or "fault", and gave him the courtesy name "Gaizhi", which means "to correct". Guo Jing hopes that Yang Guo would redeem the Yang family's honour, which has been tarnished by Yang Kang's villainy. He also promises Mu Nianci that he will teach Yang Guo martial arts when the boy becomes older.
