Definition
This is a four-character idiom (chengyu) meaning that extreme sincerity can overcome even the hardest obstacles. The literal image is 'metal and stone crack open' — a metaphor for how genuine persistence or honesty can move even the most unyielding person or situation. You often see it in the longer phrase 精诚所至，金石为开 ('Where sincerity reaches, metal and stone crack open'). Use it to emphasize that determination and sincerity can achieve the seemingly impossible.
