In actuality, even without meeting the two, Hua Yuanming and Gu Hongxin, the so-called phrase "This is someone Big Brother wants to kill" is absolutely fabricated.
Why would Gan Jinming say such a thing?
Xia Wenjin also visited Gan Jinming. He appeared utterly grateful to Hua Yuanming and Gu Hongxin, demonstrating what righteous heroes they are, standing up against injustice! He repeatedly emphasized that they are benefactors to him and his sister, whose kindness they could never repay in several lifetimes!
If Gan Jinming had turned against them then and there, accusing Hua Yuanming and Gu Hongxin, it would have been easier to handle. But he didn't. He repeatedly referred to them as great benefactors who avenged him and his sister, as great benefactors of the Gan family!
