人丑嘴不甜长得磕掺还没钱人懒就嘴甜长得一般就爱钱
[rén chŏu zuĭ bù tián zhăng dé kē chān hái méi qián rén lăn jiù zuĭ tián zhăng dé yī bān jiù ài qián]
A rather cynical and self-deprecating expression translated roughly as 'If ugly, I don't flatter; if short on appearance and money, then lazy and unfriendly; if average looking then only interested in money', conveying dissatisfaction or resignation towards one's attributes and attitudes.
