Above article refers to the house churches often cited Bob Fu of CAA - “The Three Grades”, and their rival “The Eastern Light”.

These unregistered/underground Christian sects were banned by the Chinese government because they were killing people in order to retain and compete for membership.

These “cult of Christianity”, thou in name are Christian, do not even believe in the Bible. For example The Eastern Light believes Christ has returned to Earth - in the form of a invisible Chinese woman. The Three Grade’s Leader, Xu Shuangfu, actually named himself as the Messiah reborn.

Bob Fu’s and CAA’s take on that case may be found here.

Personally, I’d say the Chinese government’s track record on human rights and religious freedom denies it any credibility when proclaiming what is and what is not a “cult”.
