everyone says so; in one voice ? 殺傷疾患，十室九空。百姓怨嗟，～。(韓愈《黃家賊事宜狀》) Even the sick people were killed and the slaughter stripped nine houses out of ten bare. The common people sighed and complained in one voice.
如出一口rú chū yī kǒu
就像從一張嘴里說(shuō)出來(lái)的一樣。形容眾口同聲，說(shuō)法一樣。everyone says so, in one voice, All say the same thing.
