Who did Yang Qingjuan learn eight characters from?

My own teacher. Yang Qingjuan is from the novel "Hero Please Stay", which tells the story of a woman who stood at the peak through her own efforts in a martial arts era. In this novel, because Yang Qingjuan doesn't have her own skills, her owner teaches Yang Qingjuan the eight characters that she has been studying all her life. This novel is wonderful in content and compact in plot, and has won the love of many readers.
