See the big from the small, see the big from the small, that is to say, we should get a glimpse through the individual and explore its essence through the appearance. Only in this way can we make fewer detours on the road of construction, save as much as possible, and achieve maximum benefits at the lowest cost.

Some people are good at discovering some potential laws in daily trifles because they have unique vision and rich associations. Newton saw an apple fall from the windowsill and discovered the law of gravity. Copernicus discovered "Heliocentrism" through the common phenomenon that the sun rises and sets in the west. Bi Sheng invented movable type printing from seal cutting and burning seals. The Wright brothers invented the big bird flying from the sky to cross the ocean.

To be good at seeing the big from the small, we must first have a unique vision and learn to observe carefully. We can know people by studying the past, and we can know the yin in the hall, the trip of the sun and the moon, and the change of yin and yang. When you see the ice in the bottle, you know the cold of the world and the hiding place of fish and turtles.

We should be good at seeing the big from the small, but also have an open mind and rich associations. Give you a drop of dew, and you will imagine the freshness of dawn; Give you a cold star, and you can certainly imagine the tranquility of the night sky; Give you a spray, and you should be able to imagine the vastness of the sea. You should be able to see what people have never seen, think of what people have never thought of, see the world in a tear, and see the truth in a sentence.
