What does ancient philosophy mainly mean?

China's ancient philosophy has a long history and is profound. China's ancient philosophy sprouted in the Yin and Zhou Dynasties. In the early years of the Western Zhou Dynasty, Shang Shu Hong Fan put forward the theory of five elements, taking Jin Mu's five elements of fire, water and soil as the most basic things that constitute the world. In the Book of Changes in the Yin and Zhou Dynasties, there was the original concept of "Yin and Yang". I ching selected heaven (dry), earth (Kun), thunder (earthquake), mountain (root), fire (separation), water (ridge), ze (intersection) and wind (change) from the natural world that people often contact in their lives. In the Spring and Autumn Period and the Warring States Period, hundred schools of thought contended and became the most brilliant period in the history of China's philosophy. On this basis, many philosophers and schools of philosophy have emerged in the development of China's philosophy for more than two thousand years, each of which embodies the spirit of the times.

Different genes that have become the spiritual culture of the Chinese nation still have extensive and profound influence. Among them, the philosophical thoughts in the following four periods have the greatest influence: pre-Qin philosophy, Confucian classics in Han Dynasty, Buddhist philosophy and Neo-Confucianism in Song and Ming Dynasties. Neo-Confucianism in Song and Ming Dynasties, as an important stage in the development of Confucianism, raised the thinking level of China's philosophy to a new level, and its theoretical significance and value should be affirmed. However, after Neo-Confucianism became the official philosophy in the late feudal society, some of its viewpoints were used by the ruling class, and became tools to suppress and stifle human nature and maintain feudal absolutism, which brought profound disasters to China society and the people of China. ? After several great developments, China's ancient philosophy reached its peak in the Song and Ming Dynasties, and further development was the end of China's ancient philosophy.
