尝一脔肉,知一镌之味;悬羽与炭,而知燥湿之气;以小明大。见一叶落,而知岁之将暮;睹瓶中之冰,而知天下之寒;以近论远。——《淮南子·说山训》吃一块肉,就知道整个锅中的味道;借助羽毛和木炭,就可以知道空气的湿度。这是通过小的事物来了解大的事物。看见落叶,就知道秋天快要来到了;看到瓶中的水结冰,就知道天气的寒冷。这是通过近的事物来感知远的事物。 Taste a 脔 meat, a knowledge of the taste of Juan; hanging feather and charcoal, and know the dampness of the gas; See a leaf fall, and know the age of twilight; see the bottle of ice, and know the world’s cold; - “Huainanzi said the mountain training” Eat a piece of meat, you know the taste of the whole pot; With the feathers and charcoal, you can know the humidity of the air. This is through the small things to understand the big things. When you see the leaves, you know that autumn is coming; when you see the water in the bottle freezing, you know the cold weather. This is the perception of far things through near things.
