Ma Jin, really? Don't know much about her off-court, but she looks like such a tough tomboy on-court that it seems incongruous that she would have cuddly animal keychains.
Actually my guess is Ma Jin. I thought I saw somewhere once she had all those little toys attached to her bag. But then I could be wrong
Where was it stated that it was necessarily a girl's bag ? IIRC, men also happen to have got silly toys like that on their bags, even if it's less common.
