If she's particularly aggressive towards hands you could try taking them out of the equation for a bit.
I had the same problem with my Chinese and was getting nowhere until I resorted to taking her out of the cage by carrying her in her bed and then sitting in the bath with her. I let her climb me and get used to my smell and chatted to her. Eventually she let me stroke her and would walk on my hands and take food. Unfortunately, she passed away at 5 months before we got any further. It was a long slog
