The meaning of black gloves's white gloves
To eradicate the so-called "white gloves": in short, it is to act as a middleman for black money bleaching or a "legal" coat for actually engaging in "illegal" affairs. It is not difficult to understand from the word glove that the "hand" that really does things is hidden in the "glove". If your hands are dirty, you can't see anyone.
Then put on "white" gloves so that others won't notice that their hands are dirty. On the contrary, they may think that their hands are well protected and should be clean. So we usually look for "just" and "reasonable" reasons to cover up some shady things, as well as individuals, units and organizations. Anyone engaged in this kind of cover-up work can be called white gloves.
Europe used gloves to symbolize authority and sacredness, so early European knights wore white gloves to show that they were performing sacred official duties; Take off your gloves and hold them in your hands, indicating chic and leisure; Throwing gloves in front of each other means challenging a duel. The challenged knight picks up the gloves and announces that he will fight.
