Final Result Unreleased

During the application of one of the China universities, after some status such as "Submitted", "Under Review", "Pass the Preliminary Review", it was updated with a status called "Final Result Unreleased". The waiting of final result was suffering.
As I googled around, some say it is a status with uncertaincy - the final result could be rejected or accepted. some say it is a good sign - the overall academic review is passed. The applicant is under final review of scholarship.
I got so confused and worried, and actually called the university. The teacher replied that "Final Result Unreleased" generally means so far so good, just wait for the final decision, but, but, ... she couldn't guarantee anything about it. So after the call, I was still worried.

It turned out to be a good sign :)
