In wine there is truth.

酒后吐真言。

Wine in, truth out.

三杯下肚，真话出口。

Truth lies at the bottom of a decanter.

酒瓶空，真相露。

What soberness conceals,drunkenness reveals.

醉汉口里露真言。

When will the moon be clear and bright? With a cup of wine in my hand, I ask the blue sky.

明月几时有，把酒问青天。

One cup more please，since you will leave now and have no old friends on your travels.

劝君更尽一杯酒，西出阳关无故人。
