Don't spread rumors about things without solid proof.
Tips
culture
实锤 is essential gossip vocabulary on Chinese social media. When a celebrity scandal breaks, netizens demand 实锤 (hard evidence) before fully believing it. 实锤了 = it's confirmed/proven.
memory
实 (solid/real) + 锤 (hammer) = a real hammer blow of evidence. Picture a judge's gavel slamming down: case confirmed!
