愚不可及

tā zǒng wèn wǒ yī xiē yú bù kě jí de wèn tí

他总问我一些愚不可及的问题。

He always asked me some ridiculous questions.

zhī qí bù kě ér wéi zhī yú bù kě jí

知其不可而为之，愚不可及。

To know it's no use, but keep on doing it. There can be no greater folly than this.

rú guǒ wǒ men tóng yì tā men bù hé lǐ de yāo qiú nà jiāng shì yú bù kě jí de

如果我们同意他们不合理的要求，那将是愚不可及的。

It would be the height of folly for us to accede to their unreasonable demands.
