Dead men tell no tales.
Sǐrén bú huì xièmì.
死人不会泄秘。

Death is the great leveller.
Sǐwáng shǐ yíqiè píngděng.
死亡使一切平等。

Deeds, not words.
Xíngdòng shèng yú kōngtán.
行动胜于空谈。

Desert and reward seldom keep company.
Gōng yǔ shǎng jué shǎo jiébàn ér xíng; shǎngfá bù míng nǎi sī kōng jiàn guan.
功与赏绝少结伴而行；赏罚不明乃司空见惯。

Desires are nourished by delays.
Kěwàng yuè jiǔ de jiù yuè xīwàng dé dào.
渴望越久的就越希望得到。

Desperate diseases must have desperate remedies.
Juézhèng xū yòng lièyào yī.
绝症须用烈药医。

Diamond cuts diamond.
Shì jūn lì dí.
势均力敌。

Discontent is the first step in progress.
Bù mǎnyì shì jìnbù de kāiduān.
不满意是进步的开端。
