A lazy sheep thinks its wool heavy.

懒羊嫌毛重

A sound mind in a sound body.

健康的思想寓于健康的身体。

Business neglected is business lost.

玩忽事业等于丢失事业。

Credit, like a looking-glass, broken once, is gone, alas.

信誉像镜子，破碎无法补。

Fine feathers make fine birds.

人要衣装，佛要金装。

He that lies down with dogs must rise up with fleas.

近朱者赤，近墨者黑。
