泛泛而谈

tā zhǐ shì fàn fàn ér tán méi yǒu xì shuō

他只是泛泛而谈，没有细说。

He only talked about it in general terms and didn't go into details.

yóu yú bù liǎo jiě xiáng qíng wǒ duì cǐ zhǐ néng fàn fàn ér tán

由于不了解详情，我对此只能泛泛而谈。

Since I do not know the details, I can only generalize about the matter.

hǎo de lì zi yǒu zhù yú bì miǎn zuò zhě fàn fàn ér tán

好的例子有助于避免作者泛泛而谈。

Good examples help to clarify a writer's thought by making the general specific.
