Catch the wind and catch the shadow bǔ　fēng　zhuō　yǐng

[Explanation] It originally means that something is as hard to catch as the wind and the shadow. There is no solid and reliable basis for saying and doing things after metaphor.

[Quote] "Book of Han·Jiaosi Zhixia": "Looking for it; it is like catching a shadow in the wind; in the end, it cannot be obtained."

[Authentic pronunciation] Catching; It cannot be pronounced as "pǔ".

[Shape Distinguishing] Shadow; cannot be written as "scenery".

[Similar meaning] Look at the wind and catch shadows, make something out of nothing, hearsay

[Antonym] Seek truth from facts, hear and see, be conclusive

[Usage] It is a metaphor for saying and doing things without factual basis. Generally used as predicate, attributive, and adverbial.

[Structure] Union.

[Analysis] ~Different from "hearsay": ~The meaning is heavier; close to imagination or fabrication; "hearsay" has a lighter meaning; there is also "listening" as the basis; but this basis is unreliable. .
