My friend laughed at my wife for being ugly. What should I do?

They laugh at you because you agree that your wife is ugly, and you don't know how to refute them. In fact, it is very important to marry a virtuous man, and superficial people will care about appearance. The wife is her own, let others say it! You must love your wife, don't always care about other people's opinions, let others know how happy you are and let them envy you.
