Generally speaking, even if it is necessary for Zhao Kunlun to relinquish his position as the head of the Public Security Bureau, the norm would be to communicate this matter privately with Zhao Kunlun and let him make the proposal himself. This way, it would be seen as a gesture of modesty and a pragmatic approach. It shows broad-mindedness and willingness to give opportunities to younger people, creating a path for them.
However, Nie Zhenbang did it differently. Without having any discussion with Zhao Kunlun, he brought up the matter directly during the standing committee meeting. This left Zhao Kunlun not only shocked but also irate. Doing this was undoubtedly a slap in Zhao's own face and made people assume Zhao has an excessive hunger for power and has been longing to monopolize this position.
