nature is not only the main source of human material life, but also an important sustenance of human spiritual life.

when a person is afraid of adversity because of the hustle and bustle of the city, he needs to return to the embrace of nature and enjoy the rare peace and comfort.

The slogan "Back to Nature" put forward by the 18th century European romanticism contains a detachment of dissatisfaction with the reality of capitalism.

The earliest discovery of the beauty of landscape vegetation in China is inseparable from morality and beauty.

More than 2, years ago, Confucius put forward the saying that "the benevolent enjoys Leshan, and the wise enjoys water". This is a metaphor for the broad and loving mind of the benevolent and the intelligent and clever character of the wise with the flow of water, which created the so-called "Bide" theory in ancient times.

in the Han dynasty, Dong Zhongshu further developed and compared the characteristics of water to all kinds of personalities. He said: "Water is the source of chaos, which is inexhaustible day and night. It is like strength, and it is like a fair person. Follow the micro-direction, without leaving a small question, which is like an inspector; If you don't follow the valley, or play Wan Li, you will come, which is both a knower; It is know life who can prevent the mountain and please clean it; Unclear entry, clean exit, is both a good person; Going to the valley of the child, entering without doubt, is like a brave man; Everything is caused by fire, and water alone wins, which is both a warrior; It is both virtuous to be born with salt and die with loss. " Here, the water source is inexhaustible, which means the power of people; When the water is full, it flows, which means the fairness of people; Everywhere, it is a metaphor for people's insight; Being far from being fascinated is a metaphor for human wisdom; The mountain is blocked and clear, which is a metaphor for people's safety; Turning turbidity into cleanliness is a metaphor for people's good teaching; There is no doubt about going into the valley, which means that people are brave; Being able to overcome fire alone is a metaphor for the strength of people; Where there is water, there is life, which is a metaphor for human virtue. This includes all the saints' moral qualities in Confucianism.

Of course, natural beauty has not been regarded as a completely independent aesthetic object in the stage of "Bide".

since the Wei, Jin, Southern and Northern Dynasties, a large number of scholars and scholars have lived in seclusion in the countryside, swam in the mountains and rivers, and sought the pleasure and spiritual sustenance in nature, thus forming the earliest school of pastoral poetry. At this time, nature and beauty have entered the aesthetic field of human beings, become independent aesthetic objects and become an indispensable part of human spiritual life.

Indeed, natural beauty plays a unique role in cultivating people's minds and sentiments. Natural beauty, quiet and simple nature can make people wash their minds, return to simplicity, get rid of the shackles of secular society, "only the house of sex, really take the shackles of the Buddha", and practice a life practice that is indifferent and pure, and "don't care about the poor, don't draw on the rich", which is the kind of wild interest that our ancient people appreciated.

The majestic and lofty sight of natural beauty can inspire people's courage to forge ahead and set up lofty and lofty ambitions.

Kant once said: "The steep cliffs that seem to overwhelm people, the dark clouds that burst out in the sky like thunder and lightning, the volcanoes with destructive power, the storms that sweep away everything, the Wang Yang sea in stormy waves, and the waterfalls dropped from huge rivers make our resistance pale and insignificant under their power. But as long as we feel safe, its shape and horror are attractive, and we will gladly regard these objects as lofty, because they raise the strength of our hearts beyond the usual prosperity, which makes us show another kind of resistance and have the courage to compete with this superficial omnipotence of nature. "

Hugo praised Shakespeare as a genius. "Like all people with great powers and great intelligence, Shakespeare poured the whole nature into his own glass. He not only drank it himself, but also asked you to drink it.". This kind of praise is also well-deserved for the outstanding bold poets in China. Li Bai said that "the Yellow River falls to the East China Sea, and Wan Li writes it in his mind", and Meng Jiao said that "heaven and earth are like chests, and the wind and thunder are born". Throughout the ages, the beautiful mountains and rivers of the motherland have inspired the ambitions of many patriots. "There are so many beautiful mountains and rivers that countless heroes are bent over." When the contemporary painter Liu Haisu climbed the high mountains on the East China Sea, he once wrote a poem "The sea reaches the end, and the mountain climbs to the top, and I am the peak." From the vastness of nature, he inspired his fighting spirit of daring to climb, showing a lofty life value.

Nature also contains infinite profound philosophy of life, which is enough to inspire people's minds and make them think. He is the best enlightenment teacher for mankind.

As the English poet Blake said, "To see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an instant."

The laws of nature's metabolism itself are enlightening people to a state of being poor, changeable and complacent.

Confucius realized that life is hurried and precious from the endless river, "the deceased is like a husband, never giving up day and night".

Tao Yuanming is haunted by a cloud bird, which reminds him of his life destination. Wang Wei's "I will walk till the water checks my path, then sit and watch the rising clouds" seems to imply that people should wait for opportunities in due course; Bai Juyi's "It's late to learn from Sang Yu, for the sky is still full of clouds" warns people to cherish their old age and glow with brilliant life.

In addition, like Du Fu's "Come to Liang Shangyan by yourself, make a blind date with a gull in the water", like Li Shangyin's "though I have for my body no wings like those of the bright-coloured phoenix, yet I feel the harmonious heart-beat of the Sacred Unicorn", like Liu Yixi's "The sinking boat crosses Qian Fan, and the sick tree leads Wan Muchun", like Su Shi's "I don't know the true face of Lushan Mountain, but I am only in this mountain", don't I realize the philosophy of life from natural images?

aren't all the changes in nature, such as "white clouds and pale dogs", "vicissitudes of life", "rather critical" and "mushrooming", all signaling people to integrate their lives with nature and achieve the superb realm of blending things with me?
