I suspected that this was the reason.

I look forward to seeing that with interest. But remember, just making
the warnings more scary is simply like shouting "YOUR HOUSE HAS JUST
BEEN BURGLED" instead of saying it. You have to either not load the
page, or at the very minimum, not send any authentication information.
Also, if you load the page, users may be tempted to click through or
ignore the warning because "the page looks right". Users should not be
required to understand the threat model of MITM. Not showing them the
page avoids this understandable tendency.
So I would urge Qihoo 360 to a) update their browser not to load the
page when there is a certificate error; and b) work with CAs and sites
within China to improve the use of SSL certificates.
