有两个成语:一个是“一叶知秋”,一个是“蛛丝马迹”。细想的确意味深长。无论是“从一片落叶可以觉察秋天的到来”,还是“从蹄印蛛丝可知马的去向和蜘蛛的所在”,包含其间的道理都发人深省,这就是,只要善于观察,善于分析,就足以从看似微小的痕迹中发现某种重要的规律或秘密。 There are two idioms: one is “A leaf knows the autumn” and the other is “a clue.” Thinking about it really means a lot. Whether it is “from a piece of fallen leaf can be aware of the arrival of autumn” or “the whereabouts of horses and spiders can be seen from hoof prints and spiders”, the reasoning contained therein is thought-provoking. That is, as long as you are good at observation and good at analysis, it is sufficient. Some important rules or secrets are found in seemingly tiny traces.
