They are just a teacher and a student.Sun Toutou is an orphan without parents, and Ren Xinzheng's son is Ren Tianzhen. They met during the fight against injustice.Ren Xinzheng took a fancy to Sun Toutou's potential and wanted her to learn Chinese medicine, inherit his legacy, and promote Chinese medicine culture.

In addition, Sun Toutou’s mother is the descendant of Jiang’s acupuncture and has very good medical skills. However, both his parents died saving lives. From then on, Sun Toutou became an orphan.
