How to look at a leaf knowing autumn, what is the true meaning of a leaf knowing autumn

I look at the autumn of a leaf in this way, from the fall of a leaf can see the arrival of autumn, a person can see from the small things in the future to see the big things in the future.

When you see a fallen leaf, you know that autumn is coming. The metaphor predicts the development trend and change of things from some subtle signs.

One leaf knows autumn, and its source is "Huainanzi Saying Mountain Training".

See a leaf fall and know that the year will be twilight. Song Tang Geng's "Wenlu" quoted Tang poetry: "Mountain monks do not understand the number of Jiazi.

A leaf falls to know the world in autumn. ”

The role of leaves includes the following aspects:

1. Respiration.

The leaves of the plant breathe through the stomata on the leaves, and air can enter and exit from the stomata, diffusing the inhaled gases to various parts of the tree to meet the needs of growth.

2. Photosynthesis.

The role of leaves also includes photosynthesis, and in the leaves of plants there is a small green particle called chloroplast.

Chloroplasts can photosynthesize and fight for oxygen for their own growth, which is what distinguishes plants from animals.

3. Nutrient conversion: Plants can inhale carbon dioxide from the air through the stomata on the leaves.

It also draws water from the soil through its roots, which in turn transports water to the leaves. Carbon dioxide and water meet in the chloroplasts of the leaves, and sunlight converts them into nutrients such as starch, which makes the trees grow more vigorously.

4. Transpiration: The transpiration of leaves is a major driving force for the absorption and transportation of water by plants, especially for tall plants, if there is no transpiration, it will not be able to fight for water for itself, which will cause water shortage at the top of the tree, and will lead to the death of trees in serious cases.

Autumn means that rainfall, storms, etc. tend to decline or decrease, and everything in nature begins to grow from lush to mature. The beginning of autumn does not mean the end of the hot weather, the so-called "hot in the dogs", according to the calculation method of "the three dogs", the beginning of the autumn to the summer is often still in the "three dogs" period, so the weather in early autumn is still very hot, and the real coolness is generally after the Bailu solar term. The watershed between hot and cool.

In autumn, not at the turn of summer and autumn. The climate in autumn is divided into two phases, the early autumn is "muggy", and the mid-autumn tends to be "dry" and "cool". In general, the altitude angle of the sun enters autumn.

Gradually lowering, the temperature gradually decreases from heat; The autumn breeze is cool, the scorching heat is gone, the fruit is full of branches, and the fields are golden.

Autumn is the harvest season, and many plants mature in the fall. In the autumn season, in nature, the yin and yang energy begins to change, the yang energy gradually recedes, the yin energy gradually grows, the climate turns from hot to cold, and everything grows with the cold and gradually declines, which is the season of alternating heat and cold. As temperatures drop, the leaves of many deciduous perennials will gradually change color, wither, and fall, leaving only the branches to survive the winter.

The annual herbaceous plants will come to the end of their lives, withering and dying. Seasonal transitions encompass many climatic characteristics, and it is inaccurate to judge autumn based on temperature alone. The most noticeable change in autumn is when the leaves of the plants change from lush green to yellow, and begin to fall and the crops begin to ripen.

The true meaning of "knowing autumn in one leaf" refers to the development trend and results of the whole situation through individual subtle signs; It is generally used as a definite sentence in a sentence.

The original meaning is to know the arrival of autumn from the fall of a leaf.

Song Tang Geng's "Wenlu", Chen Yuanliang's "Guangji of the Year" volume 3 quotes Tang poetry: "The mountain monk does not understand the number of Jiazi, and a leaf falls to know the autumn of the world." ”

The idiom story of a leaf knows autumn:

Enlightenment people focus on carefully understanding the details, details can reflect a lot of relevant information, a detail can represent the overall development situation and the likely outcome. Everything is related, and if there are signs of the details of the present, there will be corresponding results, except for special accidents, of course. However, these are all possible things, and sometimes, observing things only on the surface, at the surface, will delay the fact.

The "one leaf" of "one leaf knows autumn" may be a leaf that was destroyed by moths in the spring and fell down, so "one leaf knows autumn" is just a judgment made in vain. Seeing is believing, hearing is false, and there are mistakes, "a leaf knows autumn", it may also be an accident, after all, everything is possible.

<> "A Leaf State Closed to Know Autumn."

Picked up a bunch of autumn leaves.

Use large leaves to make grass for closure.

Make a big tree out of colored leaves.

I like leaves, and every time I collect them, I will put them in books, and many books will have various leaves, mainly ginkgo biloba leaves and maple leaves.

Today, at the beginning of autumn, the rain has been falling intermittently, and when I returned home, I suddenly remembered that I wanted to pick up a leaf for this special day as a souvenir, and immediately went downstairs to look for the leaves. Because I was in a bit of a hurry to go out, I didn't bring an umbrella, braved the drizzle, looked for leaves that could represent the color of autumn in the community, and stumbled upon the plane tree leaves falling in the bushes. When I returned home, I didn't expect that it was a leaf that knew autumn, and it was a sycamore.

The mountain monk does not understand the number of nails, and a leaf falls to know the autumn of the world. Since ancient times, the sycamore is regarded as a holy king and a prophet, and the sycamore is said in the "Flower Mirror": "This wood can know the age, and the tung will start after the Qingming Dynasty."

Tong Buhua, the year will be cold. At the beginning of autumn, a leaf falls first. Therefore, there is a sentence of "a leaf of sycamore falls, and the world knows autumn".

Since then, I have a deeper understanding of the leaves of the plane tree.

So from a psychological point of view, what characteristics of perception does "a leaf know autumn" refer to?

The four properties of perception are holistic, selective, constancy, and comprehension.

1.Selectivity.

In the process of perception, the property of people distinguishes the perceptual object from the background and responds clearly and preferentially is called the selectivity of perception.

For example:1When reading a book, the circled words are the objects of selection, and the uncircled words belong to the background.

2.A little red in the greenery, a soldier in camouflage uniform in the grass.

2.Wholeness.

The object of perception is composed of different parts and attributes, but we always perceive objective things as a whole, that is, we synthesize the individual characteristics of objective things into a whole to reflect, which is the totality of perception.

For example: "Leopard in the tube", looking through the bamboo pipe and seeing a leopard print, it is speculated that there is a leopard on the opposite side. Because the leopard print on the leopard belongs to the part of the object of perception with high intensity.

3.Comprehensibility.

In the process of perception, people always interpret the object of current perception according to their existing knowledge and experience, and describe it in language to make it have a certain meaning, which is the comprehensibility of perception.

For example: "There are a thousand Hamlets in the eyes of a thousand readers", different people's knowledge and experience are different, so people will always use their own knowledge and experience to understand the object of "Hamlet".

4.Constancy.

In the process of perception, when the conditions of perception change within a certain range, the image of human perception still remains relatively unchanged, which is called the constancy of perception.

For example, when the car is close to us, we think the car is big, and when the car is far away from us, we think the car is small, but we know that the size of the car has not changed.

Thank you for this sycamore leaf, you were seen by me, and I gave me another gift - awareness.
