Not surprisingly, she finds the current Women's World Championship system unfair:
I am satisfied with my play in the match but I cannot say that I have only positive feelings – after all, to me the current Women's World Championship system seems to be unfair. And I believe I'm not the only one who thinks like this. It would be good if the current system changed to a more reasonable format. I am sure, a "real" World Championship Match would attract much more attention.
It turns out, however, that there is an actual reason why the current system is in place. It's a sensible reason too, though I'm not inclined to think it's a sufficiently good one:
Actually, last month I officially made a proposal to FIDE to change the format of the Women’s World Championship. I suggested three reasonable alternatives but the answer I received seems to indicate that my proposal was not accepted. The main reason why they want to stick to the current system is the fact that it is easier to find sponsors if you call the knock-out tournament “World Championship”. If you called it "World Cup" it would be extremely difficult to find sponsors.
So there you have it. Anyway, now that Hou has finished her degree look for her to make a big push for 2700 in the next year or two, after which she may well follow in Judit Polgar's footsteps and ignore women's events. (At least if the Chinese sports officials let her.) There's a bit more to the interview than this (but not much), so have a look.
