Abstract
Gu Jiegang devoted the energies of his lifetime to researching and debating many of the major books and records of ancient China, and advocated the well-known theory of "doubting of antiquity in order to discriminate the false". The objective of the project was to give the ancient writings back their true features, revealing the true spirit of China's traditional culture, and preventing the latter from being confused and corrupted by false theories. His achievements are clear and indisputable. Just as the venerable Guo [Moruo] once said: "He has, by and large, laid bare the falsities of old historical materials".
