Hua Tuo
Years after her son's death, she was visited by Ma Chao and his friends when Guan Yu's arm was poisoned. However, she refused to treat his arm once she hears Ma Chao's name. Ma Chao solves things out with the famous doctor, and she eventually forgives him. However, she still insists on not treating Guan Yu's arm. This makes her only apprentice, Hua Tuo, take her place in curing Guan Yu. Knowing that she has taught Hua Tuo everything he needed to know, she retired and Hua Tuo became her successor.
