it's just that bitcoin was pretty anonymous, but there are more convenient ways to get money outside if you wanna avoid wire transfer through Chinese person
you can find friendly shop abroad willing to charge your card fake sale for commission and bank fees, until recently this was petty much unlimited by those 50K USD yearly limit per person, but I think they put there already some limit
there is also 100K RMB per bank card yearly withdrawal limit, so there is that
personally I just maxxed limits of my wife through years to get money outside China even without involving extended family, my own account in China stands on 130RMB now :))
