The twenty-four solar terms are the knowledge system and practice formed by the Chinese people observing the annual movement of the sun, embodying the wisdom of the thought of responding to the times in accordance with the heavens, and are the distinctive mark of the excellent traditional Chinese culture, which is the concentration of the Chinese civilization and the wisdom of the Chinese people, it has a very important value in traditional Chinese culture.

When I was a child, the Seasonal Song was considered a children's song for initiation and education. Walking along the country road or sitting in the adobe-walled classroom, a group of children would sing loudly: "Spring rain wakes spring with pure grain bequest. Summer grain buds and ears flourish in summer heat. Autumn heat abates with dewy autumn and cold frost. Winter snow, heavy snow, winter cold descends."

The 24 solar terms, which have been passed down for more than 2,000 years, are a surprisingly authentic blend of the generations of Chinese people's simple view of time, profound view of nature and open-minded outlook on life. The Chinese people have been extremely wise in linking the solar terms with survival and life, and have used the solar terms to grasp the laws of time and guide agricultural production. However, the profound meaning of the festival is far more than that, it is also closely and deeply connected with the poetic temperament, aesthetic character and value pursuit of the Chinese people.

Now that I think about it, the education on festivals was so sincere in the beginning. The festivals have the flavor of earth and nostalgia, traditional customs and the joys of farming. More importantly, while summarizing the seasons, people began a long journey to discover the spiritual world, leaving behind a wave of vitality in the river of ages. Even today, as we move from "eating by the sky" to the agricultural production mode of "knowing the sky", the festival complex is still deeply rooted in people's hearts. Moreover, Chinese culture is profound and colorful, and the wisdom of the festival culture should be infused into everyone's heart.

The 24 solar terms contain the Chinese sense of cherishing time. Cherishing time is an ancient and enduring belief of the Chinese nation, and it has been the attitude of generations of Chinese people towards time. In The Analects of Confucius, it is said, "Time passes, time will not wait for me." The Spring and Autumn Annals of Lu Shi says, "Cherish time; do not rest until you are old; do not rest until you are sick; and do not give up your career until you are at the end of your life." The Chinese nurtured a sense of urgency and perseverance long ago, and regarded time as very important. The 24 Solar Terms is, first of all, a book of time. It is the basic time pointer of agricultural production activities in the traditional period, which is a figurative expression of time based on the understanding and grasping of the laws of nature. Its appearance fully testifies to the spirit of historical initiative of the Chinese forefathers who were brave enough to search for time, inquire about time, and grasp time, and reflects the proactive and optimistic attitude of this ancient nation in the face of existence and life in general. Especially with the evolution of history, the 24 solar terms, as a time system integrated into people's daily lives, have been subconsciously transformed into a self-regulatory mechanism, playing a stimulating role in people's introspection about time. The change of seasons has made people cherish time. In the midst of the flow of time, the wise Chinese people have tried to grasp the eternal value of their limited lives, and have sent out their feelings about the seasons and philosophical thoughts about life countless times. Poet Li Yi in the Looking into the Mirror the Day Before Autumn wrote: "All past events can be written off, career are reflected in this mirror. Now I only have white sideburns, and tomorrow is the beginning of autumn again." The poet Yuan Zhen wrote in Singing 24 Solar Terms Poems——White Dew August Festival, "At the time of White Dew, the dew sticks to the sparse autumn grasses, and at this time the sky is very blue and the white clouds are very sparse. The leaves of the trees drift down slowly with the autumn wind, and suddenly I realize that my sideburns are already graying. The birds began to prepare food for themselves to survive the cold winter, and I was just a passerby, like a useless piece of artemisia. The crops in the fields had ripened, and I rushed to gather grain, but I could only finish my work if I busied myself from morning to night." Here, the solar term is a time symbol, and as if it were a life symbol. Sentimental poets, in the passage of time to ponder the true meaning of time, thinking about the meaning of life. And what does it mean to ordinary people? Proverbs say, "Before and after the Qingming Festival, plant some melons and beans," "Plow the land in the beginning of autumn, and the seeds will be fuller," "In winter, block the pens of livestock," and so on, also show the industriousness and simplicity of Chinese working people.

The 24 solar terms contain the Chinese people's sense of honoring heaven and loving people. At the opening ceremony of the Beijing 2022 Winter Olympics, the countdown to the 24 solar terms as the opening program attracted the world's attention. For a while, the twenty-four solar terms became a hot topic. Starting from the perspective of traditional Chinese culture and choosing the 24 Solar Terms as a "Chinese symbol" to open the Winter Olympics, what were we conveying to the world at that moment? In the picture, the flow of time, the four seasons are in order, the seasons are changing, beautiful mountains and rivers are intoxicating, the Olympic athletes are inspiring, the ordinary people in the story of pursuing the dream are touching, and a quiet, peaceful, happy, beautiful picture is like the spring rain infiltrating the bottom of the heart, which makes people forget to come back home. To honor life by respecting the nature of heaven and earth, and to follow the law of placing life in the nature of heaven and earth, this is the great wisdom of the Chinese people. What we convey is the respect of nature, the pursuit of truth and beauty, the love for people, and the cultivation of goodness. This spirit expressed by the ancient Chinese culture is deeply embedded in the 24 solar terms.

Although the 24 Solar Terms are astronomical calendars, they also have profound humanistic significance. It is precisely because of this combination of astronomical and humanistic significance that the 24 Solar Terms are more representative of traditional Chinese culture. When explored, traditional Chinese culture also begins with the contemplation of the relationship between heaven and man. Zhang Lei, a writer of the Northern Song Dynasty, wrote in his Record of Entering the Learning Lodge that he "looked at the ways of heaven and earth and scrutinized the reasoning of all things in order to explore the subtleties of morality, and did not stop for a moment, so their morality progressed every day." It can be seen that astronomy and humanities are inseparable, and astronomy and humanities can observe each other in order to explore the laws. In such a cultural tradition, the 24 Solar Terms are naturally endowed with the profound connotation of "respecting heaven and loving people". People revere nature and warmly feel the changes of natural seasons, and they also revere life and warmly feel the beat of life. People learn from nature, deeply realize the beauty of nature, and create the beauty of society and the beauty of the human heart by treating beauty with affection. At Qingming, when the wind is clear and the scenery is bright, people memorialize the deceased, always continuing the spiritual beliefs of thousands of years and cultivating the spiritual and cultural soil. At winter solstice, the Book of Han wrote: "winter solstice season, Yang Qi began to be born, the monarch began to use the right way to govern the country, which is worth celebrating" How to celebrate? Nowadays, more and more people in the society are willing to volunteer and go to the community, elderly homes, etc. to make dumplings for the widows and orphans, which is the humanistic flavor of the solar terms. Festive culture inherited to today, to promote its creative transformation, innovative development, we must make it compatible with modern life, to let the festival complex from the simple sense of cultural nostalgia to a cultural self-awareness based on cultural confidence.

Since the 20th CPC National Congress, the CPC Central Committee, with Comrade Xi Jinping at its core, has attached great importance to the inheritance and promotion of outstanding traditional Chinese culture, and has made a series of major decisions and deployments in this regard to promote the outstanding traditional Chinese culture to continuously make new achievements and create new experiences. General Secretary Xi Jinping has pointed out, "From the agricultural festivals with Chinese characteristics to the ecological ethics of the Way of Nature and the unity of mankind; from the distinctive houses and villages to the ingenious agricultural landscapes; from the festivals with a local flavor to the colorful folk arts; from the ancestral family tradition of cultivating and studying, and the ancestral family motto of father's benevolence and son's filial piety to the folkways of mutual assistance and honesty in the community, all are distinctive symbols of Chinese culture, and all of them have a distinct identity. All of these are distinctive markers of Chinese culture, carrying the genetic code of the Chinese civilization and manifesting the wisdom and spiritual pursuit of the Chinese nation." As a product of agricultural civilization, the 24 solar terms vividly manifest the spiritual pursuit of the Chinese nation, is the crystallization of the wisdom of the Chinese people, we should pass it on, carry it forward, so that the ancient wisdom in the new era, in the vast land of China, can blossom bright light and vitality.
