一、信口雌黄比喻不顾事实,随便说话。雌黄,又称鸡冠石,主要成分是三硫化二砷(As2S3),是柠檬黄色晶体,难溶于水,可制颜料。古代人写字用的纸是黄色的,写错了字,就用雌黄碾成粉末,加水调成糊状物,涂在错字上,干了再重新写。因此,称乱改文字、乱发议论为“妄下雌黄”;称不顾事实、随便乱说为“信口雌黄”。 First, let’s talk about the facts and talk about them regardless of the facts. Female yellow, also known as chicken crown stone, is mainly composed of arsenic trisulfide (As2S3). It is a lemon yellow crystal that is hardly soluble in water and can be used as a pigment. The paper used by the ancients for writing was yellow, and when it was mistyped, it was crushed with female yellow, added water to make a paste, and applied it to typos, dried and rewritten. Therefore, it was said that the text was changed indiscriminately and the argument was sent out as “give up.”
