In an interview last year she said: ‘My parents definitely have high expectations. In anything, not even just tennis. I have to be the best, do the best I can.
‘When I was younger it was to please them, but now it’s great for me to do it on my own – that’s where I think I see the best results: when it’s me driving it.
‘They both came from academic families and in tough countries growing up – my dad in Romania and mum in China.
'They were both communist countries, so education was kind of their only option. They want me to have options, they think my education is very important for my future.’
‘I have high standards. That’s helped me get to where I am in terms of tennis and also in terms of school results,’ she says.
The teenager, whose only treats are peanut butter and a solitary square of dark chocolate, reckons she’d probably be a lawyer if she wasn’t so focused on tennis.
She’s spoken about how her dad threw her into every activity at a young age, from ballet to horse riding, swimming, tap dancing, basketball, skiing, golf and go-karting – as well as tennis.
‘My dad wanted to give me a diverse skill set and I was quite a shy girl and he wanted to get me out of my shell.
'As I started winning in tennis, tournaments would take up the weekend so these other activities couldn’t happen any more, and tennis took over.’
‘I think one of my best qualities is I’m pretty scrappy and gritty and they’re two words I would describe myself as,’ she declares.
