That's another stereotype I'm disinclined to buy into. Anyway, Zhu Ting is the biggest star in volleyball; if she had really insisted that she needed more extensive treatment or time off, I'm sure her demands would have been accommodated.
If she's obedient by nature and would do anything her superiors told her to then she is still to blame for what happens to her own body.
another reason I think is Zhu Ting feels indebted to JLP for she was that one who gave her the break. JLP kinda discovered her. Picked her out from a provincial club , trained under her then to the national team. JLP must had manipulated her position / authority over ZT who treated JLP as a motherly figure and trusted her. JLP want to cement her legacy / power/ influence and knowing ZT is the force that can make it possible. She also wanted to retire with a bang.
