Make a heart for heaven and earth, make a life for the people, link the past with the future, and create peace for all generations. -Zhang Songzai is willing to open a peaceful ceremony, but the sergeant is not smooth, and his talents and ambitions cannot be displayed. He can only give lectures, write books and create ideas. Calligraphy is an inherent art in China, and our younger generation should inherit it as much as possible. These four sentences can best express the thoughts of Confucianism and show their consciousness and ambition, so they can be said to be the highest ambition of human education. But these four sentences are hard to say. A little explanation today may be helpful to young students. (1) the heart of heaven and earth: heaven and earth are unintentional, but endless, and biochemical things are the heart of heaven and earth. Therefore, Cheng said, "Heaven and earth are unintentional, but creatures are the heart." He said, "Heaven and earth were formed unintentionally." Because the biochemistry of heaven and earth is only the natural popularization of the virtue of life, it is not intended to give birth to such a vast world. So it is "unintentional" and "Chenghua". Unintentional and intentional (taking biology as the heart) is people's kind concern for the virtue of heaven and earth. Through people's attention and guidance, the heart of the universe will be highlighted. (2) Born for the people: There are two levels of life: rational life and energetic life. Life at both levels cannot be harmed or abandoned, and must be based on safety. The way of "settling down and living" advocated by Confucian sages is precisely for strangers. With this Tao, "people can't know it every day", but it can be imperceptible. Coupled with ethical, political and religious facilities, primitive people's lives can be followed, so that they can protect their lives and be loyal to their lives. This is "creating a life for primitive people". (3) The past is unforgettable: the learning of Confucian sages, from the Han Dynasty, and Wei and Jin Dynasties, and the Southern and Northern Dynasties, and the Sui and Tang Dynasties, failed to continue the learning pulse of Confucianism in the pre-Qin period for thousands of years. Neither the light of life nor the wisdom of philosophy can be revealed. Especially in the late Tang and Five Dynasties, the cultural life of Chinese people shrank and degenerated. Until the early Northern Song Dynasty, there was no decent teacher in the world. It is not an exaggeration to say that "learning and losing your way". It was not until the Neo-Confucianism came out that the metaphysical wisdom of pre-Qin Confucianism was revived, and the knowledge of life of Heaven (the meaning of mind and nature) and the teaching of becoming a virtue from inner saints were reappeared. The ideological leadership was taken back from Buddhism, and the status of Confucius naturally reappeared. The achievement of this step is unique in the history of human culture. It is a pity that since the Qing Dynasty, scholars have been humble in heart, but criticized Neo-Confucianism, which is really a great regret for academic ingratitude. (4) Creating eternal peace: Confucianism takes "the inner sage as the essence and the outer king as the function". The great function is to make peace and prosperity. Not just for a moment, but for a thousand years. The word "Taiping", like "Taihe", is the most profound concept adopted by Zhuang Mu in Confucianism. However, although Confucianism has the great aspiration of eternal peace, it can also discuss the benevolent policies of the world on the level of "Tao", but it only manages the Tao in the system, but fails to create "political Tao". Nowadays, the system of democratic politics is only a peaceful track on the political level. Coupled with science, we can achieve the requirements of "opening things up" and "making good use of students". The combination of democratic science with Confucian education of rites and music and the concept of "harmony but difference" will indeed create infinite beauty for the human world.
