Legend has it that there was once a water monster called Yu (yù 蜮). It had norns, a shell, wings and three legs, but no eyes. There was a catapult in its mouth. If Yu heard the steps of a man, it would shoot sand from its mouth at him. If even the mans’s shadow was hit, the man would fall ill.
This idiom indicates vilifying people by insinuation.
傳說江淮間出產(chǎn)一種很特別的甲蟲,名叫蜮,又有人稱做射工、射影、短狐、水狐。這種蟲常常傷害人,形狀很是奇怪,背上長著硬殼,頭上有角,身上長有翅膀,可以飛到上空,在人的頭上施行襲擊。它沒有眼睛,但耳朵聽覺特別靈敏,口中有一橫物,形狀像弩,只要聽到人聲便知道人的所在方向和距離,然后用口中所含的沙當(dāng)作矢,向人射擊。被蜮射中的人,會染上一種毒質(zhì)而生瘡;就算人的身體能夠射避,而影子被蜮射中,也會生病。
含沙射影【翻 譯】to make oblique charges.
