Many authors caution the sons of wealthy families against forming "fair-weather" friendships based on drinking and feasting. The famous Qing dynasty general Zuo Zongtang left a stiff warning to his sons: "If you make debauched friends, who are at the theater one day, at the tavern the next, and who even indulge in gambling, whoring, and opium, then you are the dregs!"
恭默的德性，還可以表現在「慎交遊」上，富家子弟唯恐交上酒肉朋友，清朝名將左宗棠就痛飭兒子，若「好交結淫、逸友，今日戲場，明日酒館，甚至嫖賭、鴉片無事不為，是為下流種子！」
