During China‘s New Cultural Movement, the Great War (World War I) not only led to the overall crisis of Western Imperialism, but also brought forth a more serious national crisis to China. It was a great shock to the Chinese intellectuals with global visions, whose reflection of the Western Civilization developed to the Sino-West Cultural Debate, the Science-Metaphysics Debate, and the critical reconstruction of modernity. Du Yaquan pointed out the "pathology" of the Western Civilization and advocated a reconciliation of Chinese and Western cultures for the rebuilding of a New Civilization. His thought on civilization was not restricted by the then prevailing modern-time order. Nor did it rely on the concept of nation-state and irrationalism. It was based on the foundation of Chinese thoughts to ponder over "Tian Xia（Land under Heaven）” puzzles and China’s issues, which left abundant ideological legacies for the construction of post-war world civilization.
