吱声

rú guǒ nǐ bù liǎo jiě qíng kuàng nà zuì hǎo bié zī shēng

如果你不了解情况，那最好别吱声。

You'd better keep silent if you don't understand facts at all.

wǒ wèn guò tā jǐ cì tā dōu méi zī shēng

我问过他几次，他都没吱声。

I asked him several times, but he didn't say anything.

tā méi jīng dǎ cǎi de zuò zài dì shang dī zhe tóu bù zī shēng

他没精打采地坐在地上，低着头，不吱声。

He sat on the ground listlessly with his head hanging and said nothing.
