This is either a strict idiom or a compound word, but it can still be used as a good word in a sentence.
Idiom is a major feature of traditional culture in China, which has a fixed structure and a fixed sentence, indicating a certain meaning. It is applied to a sentence as a whole, with subject, object, attribute and other components. A large part of idioms are passed down from ancient times and represent a story or allusion.
Some idioms are just a miniature sentence. Idiom is a ready-made word, similar to idioms and proverbs, but slightly different. Idioms are a bright pearl in China culture.
Words are the combined names of words and phrases, including words (including words and compound words) and phrases (also called phrases), which constitute the smallest structural unit of sentence articles.
