How to understand the orpiment in the mouth?

Orpiment is a monoclinic ore, the main component is arsenic trisulfide, which is highly toxic. During the Wei and Jin dynasties, metaphysics flourished, and immortal cultivation behaviors such as alchemy and taking Wushisan were prevalent among high-level Qing talkers. The discovery of a large number of mineral pigments in China benefited from alchemy.

However, the color of orpiment was similar to the color of paper at that time, but it allowed the literati to discover other uses, that is, the ancient version of the correction liquid. Therefore, orpiment has the meaning of modification and smearing.

And the most direct origin of the idiom is probably Wang Yan's "orpiment in the mouth".

Wang Yan, the word Yifu, can speak, and those who are uneasy in their minds are more likely to be easy, and the time is yellow in the mouth. "Wang Yan is a famous talker in the Western Jin Dynasty. He likes Lao Zhuang's doctrine and talks about Lao Zhuang's metaphysics every day.

But it is often inconsistent and full of loopholes, and when others point out his mistakes or question them, he doesn't care, and even changes them casually without thinking. This person is very powerful, others want to use orpiment to change things, and he will come and change it at will.

So at that time, people said that he was "the yellow in the mouth". It is estimated that it slowly merged with "Xinkou Kaihe" later, and the meaning of these two words was originally roughly the same, and it evolved into today's idiom "Xinkou is not yellow.""。

The ancients used orpiment to alter words, so they called changing words and making comments indiscriminately as false orpiment, and said that ignoring the facts and casually saying nonsense was false.

Orpiment, which is a mineral.

Orpiment is a mineral, its composition is arsenic trisulfide, lemon yellow, mostly fine-grained, flake or columnar, there are also kidney-like, mostly pearly luster. In ancient times, people used yellow paper to write, and if you write the wrong word with cherry blossoms, you can rewrite it by painting it with this mineral, so this is the origin of the idiom.

Xinkou female yellow (pinyin: xìn kǒu cíhuáng) is an idiom in historical stories, and idiom-related allusions were first seen in Jin Sun Sheng's "Jin Yang Autumn" rolling sun. In ancient times, yellow paper was used for writing, and if you made a mistake, you would use orpiment and rewrite it.

Later generations used the metaphor of "believing in one's mouth" to ignore the facts, talk casually, and make judgments lightly. The idiom is mostly used as a predicate, object, definite, and adverbial in the sentence; Derogatory.

Idiom implication: During the Wei and Jin dynasties, the wind of Qing talk prevailed. Some people also advocate Qing Tan metaphysics in order to catch up with fashion, and Wang Yan is a typical representative of it:

He talks about nothingness, but he goes around stammering and camping; He talks about high words, but he is greedy for money and bribes, and accumulates private property; Relying on nepotism to climb up desperately; Even if he interprets the scriptures and reasones, Wang Yan is also unbelievable.

Although he did have some talent, this talent eventually turned into ugliness, and he ended up being buried alive. You can't easily make judgments about things that you don't have a full understanding of. Only by thoroughly analyzing all aspects of the matter can we make accurate judgments.

Be cautious in your words and deeds, and have a responsible attitude towards yourself and others.

Honest and unbelievable: both have the meaning of "casual talk". The difference is that:

"Talking nonsense" means talking casually; "False words" mostly refers to making presumptuous judgments, casually slandering and even fabricating rumors. The main reason for "opening up the river" is "not thinking"; Some of the reasons for "unthinking" are "thoughtless", but most of them are malicious.
