A society wants to keep good order, in addition to having the sound law, good ethics especially social publicethics in order in good morals to support the social order have the prominent function.
But in the QQ group or some other public places, I am reluctant to make comments on some controversial issues relevant to some sensitive aspects like ethics or so.
