If Two People Are of the Same Mind, Their Combined Strength Can Break Metal.
两人同心，其力量犹如利刃可以斩断金属。“二人”可以指兄弟、夫妻或任何当事的双方；“同心”，有共同的愿景，思想认识一致；“利”，锋利；“断金”，斩断金属。此术语比喻只要当事双方一条心，就能发挥强大力量，克服任何困难，犹言团结起来力量大。它强调的是齐心协力、团结合作的重要意义。
When two people are of the same mind, their combined strength is like a sharp blade which can cut through metal. “Two people” here could mean two brothers, husband and wife, or any two persons working together. “Of the same mind” here means the people sharing the same vision and thinking. This metaphorical term means that people of the same mind will create great strength and can overcome any obstacles. It stresses the importance of concerted efforts and cooperation, which will generate great power.
