The similar empirical knowledge of ancient Greece and ancient China produced similar theoretical insights, such as the understanding of the principle of leverage by Aristotle and the Mo Jing. However, the initial mechanical theory of ancient Greece soon developed into theoretical knowledge. Complex and the Chinese Mohist mechanics tradition was interrupted after the Warring States Period. The theory of not being good at observing, recognizing the movement of objects and forming a system is an obvious "weakness" in the ancient Chinese scientific tradition. In contrast, the Chinese achievements in solving practical problems are more prominent. The text is intended to explain:. ['Characteristics of the development of ancient Chinese science.', 'Reasons for the interruption of ancient Chinese scientific tradition.', 'Ancient China s original research on mechanics is not inferior to ancient Greece.', 'Incomplete mechanics theory is a weakness of ancient Chinese scientific research.']
