A person likes to expose his family's ugliness to the public, let outsiders judge his family's right and wrong, and let outsiders take care of his family's affairs. What kind of mentality is this?

Actually, this is the worst thing. Nobody cares about other people's affairs, but only intensifies contradictions. Outsiders only heard his description, but the actual situation is unknown. He is trying to win the sympathy of outsiders and feels that he is not easy to be recognized by outsiders. So, such a person, still have to let him have a good discussion at home, let him know that, in any case, the family talent is the most important, and if something happens, the family talent will stand on his side.
