一星半点

nà kě shì xì huó bù néng yǒu yī xīng bàn diǎn chā cuò

那可是细活，不能有一星半点差错。

That is a high precision job. There mustn't be the slightest slip.

rèn hé yī wèi jì zhě zài qí bì shēng suǒ xiě de wén zhāng li jī hū méi yǒu nǎ yī piān néng qǐ dào yī xīng bàn diǎn de zuò yòng

任何一位记者，在其毕生所写的文章里，几乎没有哪一篇能起到一星半点的作用。

Almost nothing that any individual journalist writes in his lifetime makes a jot of difference.
