They have weird things going on over there for quite a while (I
discovered the following first years ago:).

$ host -v -t A www.qq.com. ns-os1.qq.com.
Trying "www.qq.com"
Using domain server:

;; ANSWER SECTION:
www.qq.com.             300     IN      CNAME   qq.com.edgesuite.net.

Or in other words, they just don't subscribe to the typical semantics.
It makes no sense to try to apply common DNS concepts to qq.com. :)
