To those who think our Chinese source unreliable, shame on you!

The private clinic called Klinik Bethanien where Mirka gave birth to a set of twin girls has been revealed... well, sort of...

I just want to reassure some readers again that at HCFoo's Tennis Blog, we only publish news which we believe are true.

Hence our sources including those from Chinese websites are reliable ones.
