It had actually been Superintendent Ouyang's decision to have Zhang Fan become the acting proctology director. She still hadn't given up on raising Zhang Fan to become the future superintendent of Chasu City Hospital.
What would count as successful for a doctor? Becoming the superintendent of a Class A hospital would already be considered incredible. Anything higher would be a national-level expert doctor. Superintendent Ouyang already had no chance to go any higher, due to her own limitations and outside factors. For a female doctor in the border province, she could already be considered extremely successful.
