I think "no dust" is better than "no minister". The reason is that: 1\ "Dust-free \" places parents' expectation on their son's quality, while "no minister" is parents' expectation on his son's future character. In the current impetuous social stage, the character of "no minister" is not desirable. In a more civilized, rational and legal society after ten or twenty years, when I saw the name "Buchen", I felt that the young man's tutor might be a little out of my taste. A's parents are either rich or expensive, and such people may be difficult to control. B's parents may be "half bottles", which makes me doubt the young man's mentor. 3. When the son is older, he will chew on his parents' expectations from his name and judge his parents' standards. The former can obviously make him expect more from his parents.
