Huang Rong
Yang Guo's mother, Mu Nianci, taught him some of the martial arts she learnt from Yang Tiexin and Hong Qigong. However, due to his young age and his mother's demise, Yang Guo was unable to fully master those skills nor utilise them in combat. When he first met Guo Jing and Huang Rong, the latter managed to deduce that he is the son of Yang Kang and Mu Nianci by observing his movements.
