A word becomes a prophecy _ Kingsoft iciba

Spelling: y y incarnation Chen chen.

Interpretation: Prophecy refers to the predictions and omens that will be realized, generally referring to some "fierce" things and unlucky predictions. When a word is prophetic, it means that a (bad) sentence is correct, that is, "unfortunate words" (unlucky things, like cursing others).
