《易经》
《易经》是阐述天地世间万象变化的古老经典，也是博大精深的辩证法哲学书。《易经》包括《连山》《归藏》《周易》三部经书，其中《连山》《归藏》已经失传，现存于世的只有《周易》。相传伏羲根据河图洛书画成八卦，即为《周易》之来源。
《易经》记录了中国古人探索宇宙奥秘，并由此演绎出的一套完整深奥的星象推理文化，内容涉及哲学、政治、生活、文学、艺术、科学等诸多领域。上古时期，中国古人观察天象，确定天干地支、阴阳五行、八卦原理，结合时空、阴阳观念，发展成为一个系统的世界观，用阴阳、乾坤、刚柔的对立统一来解释宇宙万物和人类社会的一切变化。《易经》反映了中国古人对宇宙万物时刻变化的认识，揭示了宇宙的特性，囊括了天地间万物的发展属性。
在中国历史上，《易经》被誉为诸经之首，是中国传统思想文化中自然哲学与人文实践的理论根源，为古代政治家、军事家、学者、商业家所推崇。经过不断演绎，《易经》已成为一门哲学，描述了中国人遵循的一种“天人合一”自然生存法则，并孕育了中华民族自强不息、厚德载物的民族精神。
Yi Jing
Yi Jing (The Book of Changes) is an ancient classic expounding the changes of the universe and everything in it. It is also an enigmatic philosophical treatise on dialectics. The original Yi Jing consists of three volumes, but only one of them – Zhou Yi – is extant today, which, as legend has it, stems from the eight trigrams drawn by Fuxi based on Hetu and Luoshu.
Yi Jing records a complete set of profound astrological reasoning developed by the ancient Chinese through the observation of the universe and covers a wide range of subjects including philosophy, politics, life, literature, arts, and science. In remote ancient times, the Chinese people formulated such concepts as tiangan (Heavenly Stems) and dizhi (Earthly Branches), yin and yang, five elements, and bagua by observing the movement of celestial bodies. Based on that, they developed a systematic worldview that explained all beings in the universe and all changes in human society according to the principle of unity of the opposites, such as yin and yang, qian (heaven) and kun (earth), and hardness and softness. The book reflects how the ancient Chinese understood the perpetual changes of the universe, reveals its features and traits, and depicts how everything between heaven and earth evolves.
Regarded as the first of all classics in Chinese history, Yi Jing is held in high esteem by the ancient statesmen, military strategists, scholars, and businessmen alike as the theoretical root for the natural philosophy and cultural practices contained in traditional Chinese thinking. Through constant evolution and improvement, the ideas expressed in the book have become a philosophy. It explains the rule of living followed by the Chinese known as "man is an integral part of nature" and gives birth to the spirit of the Chinese nation – striving continuously for self-improvement and caring for all things with ample virtue.
